Also, cancer is not the only cause of death among FeLV-positive felines \u2013 they often succumb to minor FeLV-induced infections as well.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Nevertheless, <\/span><span style=\"font-weight: 400;\">feline leukemia in cats<\/span><span style=\"font-weight: 400;\"> isn\u2019t necessarily a death sentence. Cats may cope with secondary infections successfully and live relatively regular lives. Another good news is that FeLV is preventable, but the thing is, not all cat owners are aware of that.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Therefore, we\u2019ve researched the most critical FeLV facts and put them together for you.<\/span><\/p>\n<h2 id='what-is-felv-in-cats'><span style=\"font-weight: 400;\">What is <\/span><span style=\"font-weight: 400;\">FeLV in Cats<\/span><span style=\"font-weight: 400;\">?<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">FeLV is a retrovirus belonging to the family of oncoviruses along with other destructive viruses (such as feline sarcoma virus, mouse leukemia viruses, as well as some of the human viruses). <\/span><\/p>\n<p><span style=\"font-weight: 400;\">While the development of cancerous lesions is unquestionably one of the most severe FeLV consequences, it also results in other conditions such as repetitive infections, extreme neurological conditions, urinary system problems, etc.<\/span><\/p>\n<h3 id='the-lifespan-of-the-virus'><span style=\"font-weight: 400;\">The lifespan of the virus<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Outside of the host organism, FeLV isn\u2019t expected to survive for more than a couple of hours. Possibly, it will endure for two days under ideal conditions, but that is its topmost life span. Plus, just like any other virus, FeLV is highly vulnerable to heat and surfactants.<\/span><\/p>\n<h2 id='felv-transmission'><span style=\"font-weight: 400;\">FeLV Transmission<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Unlike FIV, the other dangerous feline virus with somewhat similar consequences, which can only be transmitted by entering the cat\u2019s bloodstream, FeLV is spread easily.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In short, the transmission is possible through any form of physical contact. In other words, sexual contact is not needed for this to happen. The virus is spread through interactive activities, such as grooming, sharing food dishes, using the same litter box, etc.).\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Of course, <\/span><span style=\"font-weight: 400;\">FeLV in cats<\/span><span style=\"font-weight: 400;\"> is unavoidably transmitted through aggressive contact such as biting. If a cat infected with FeLV gives birth to kittens, all of them will be affected as well.<\/span><\/p>\n<h2 id='risk-factors'><span style=\"font-weight: 400;\">Risk Factors<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Cats that interact with the infected cats are at the most considerable risk of getting infected with FeLV. Out of all the cats that come in contact with the infection carriers, kittens and younger cats are most likely to contract it. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">Of course, feral, strays, and pet cats allowed to wander around are the ones most exposed to the virus. This increases their risk of catching the virus, even though they have better chances of not getting it if they live in a single-cat household.<\/span><\/p>\n<h2 id='felv-symptoms'><span style=\"font-weight: 400;\">FeLV Symptoms<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">As previously mentioned, <a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC3509668\/\" target=\"_blank\" rel=\"noopener\">FeLV is a retrovirus<\/a>. These are the viruses able to transform the genetic material of the infected cells and turn them into tiny virus workshops. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">Such means of virus replication requires a significant amount of time, which is why infected cats may not show any symptoms at first. However, once they do, you will usually notice the following:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Appetite loss<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Bad coat condition<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Weight loss<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Gingivitis and stomatitis<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Persistent infections of the skin<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Bladder issues<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Recurrent fever<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Weird behavior due to neurological changes<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Eye diseases<\/span><\/li>\n<\/ul>\n<h2 id='diagnosis-felvfiv-test-types'><span style=\"font-weight: 400;\">Diagnosis: <\/span><span style=\"font-weight: 400;\">FeLV\/FIV Test<\/span><span style=\"font-weight: 400;\"> Types<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">There are different types of tests for diagnosing FeLV, which are also used for establishing the FIV diagnosis. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">The most accurate diagnosis is based on the combination of anamnesis (including the information on the potential virus exposure) and one of the commonly used tests. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">These are blood tests that will either determine the presence of the virus itself or its antibodies in the blood.<\/span><\/p>\n<h3 id='elisa'><span style=\"font-weight: 400;\">ELISA<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">ELISA (standing for \u201cenzyme-linked immunosorbent assay\u201d) is the <a href=\"https:\/\/www.vet.cornell.edu\/departments-centers-and-institutes\/cornell-feline-health-center\/health-information\/feline-health-topics\/testing-fiv-and-felv\" target=\"_blank\" rel=\"noopener\">most basic FeLV-identifying test<\/a> which can be performed during any visit to a local veterinary clinic. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">In essence, it is a routine procedure conducted as an initial <\/span><span style=\"font-weight: 400;\">feline leukemia test<\/span><span style=\"font-weight: 400;\">. A positive ELISA is undoubtedly a sign of virus exposure, but it cannot pinpoint the exact infection stage. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">Moreover, cats can test as false FeLV positive on ELISA if the organism is still in the phase of attempting to fight off the virus.<\/span><\/p>\n<h3 id='ifa'><span style=\"font-weight: 400;\">IFA<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Due to the sophisticated technology required for performing it, IFA (IFA (standing for \u201cimmunofluorescent assay\u201d) has to be done within a diagnostic laboratory. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">These are blood samples of <\/span><span style=\"font-weight: 400;\">FeLV cats<\/span><span style=\"font-weight: 400;\"> (as well as those with FIV) and are usually sent out from the local laboratory for further analysis.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">This takes place after a positive ELISA test to determine the exact stage of the infection (e.g., a positive IFA<\/span> <span style=\"font-weight: 400;\">means that the virus has entered the bone marrow).<\/span><\/p>\n<h3 id='felvfiv-combo-test'><span style=\"font-weight: 400;\">FeLV\/FIV Combo test<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">For several years, an innovative way of testing FeLV and FIV at once has been used, called the Combo test. For performing this test, no commercial laboratory is needed \u2013 it can be conducted at your local veterinary clinic in no more than several minutes. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">The only equipment required for performing this type of FeLV and FIV test consists of a piece of filter paper. Any changes on the paper after it comes into contact with blood drops indicate the virus\u2019s presence or absence.<\/span><\/p>\n<h3 id='when-to-test-kittens-for-felvfiv'><span style=\"font-weight: 400;\">When to test kittens for FeLV\/FIV?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">There are no age-related limitations to taking tests for FIV and FeLV \u2013 a kitten may undergo the testing at any time. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">However, the analysis does require taking some of the kitten\u2019s blood. This may be challenging for the little ones (e.g., 5-week-old kittens), so it might be wiser to wait a few months before the test is taken. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">If a <\/span><span style=\"font-weight: 400;\">kitten tested positive for feline leukemia<\/span><span style=\"font-weight: 400;\">, it usually has been infected with FeLV indeed, but this should be confirmed by re-taking the test. However, a negative test almost certainly means that the kitten has not been infected with FeLV.<\/span><\/p>\n<h2 id='progression'><span style=\"font-weight: 400;\">Progression<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">FeLV is a highly destructive virus that causes the cat\u2019s organism to be highly susceptible to various infections. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">These infections are called secondary infections (FeLV infection being the primary one). They are responsible for most of the diseases in a cat infected with FeLV. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">However, this does not occur overnight. There is a pattern of the disease progression, which is predictable to a certain extent.<\/span><\/p>\n<h3 id='early-stages-vs-final-stages'><span style=\"font-weight: 400;\">Early stages vs. final stages<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Roughly speaking, we can differentiate between early (asymptomatic) and <\/span><span style=\"font-weight: 400;\">final stages of feline leukemia<\/span><span style=\"font-weight: 400;\"> (progressive deterioration of the cat\u2019s health, usually starting with the loss of appetite and lethargy). <\/span><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400;\">More specifically, based on the immune response after the initial FeLV exposure, there are three levels of the infection.<\/span><\/p>\n<h3 id='abortive-level'><span style=\"font-weight: 400;\">Abortive level<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Seldom, a cat might get abortively infected, which means its immune system can respond to the infection effectively and completely eradicate it from the body.<\/span><\/p>\n<h3 id='regressive-level'><span style=\"font-weight: 400;\">Regressive level<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">In case of the regressive infection, a <\/span><span style=\"font-weight: 400;\">FeLV-positive<\/span><span style=\"font-weight: 400;\"> cat is a virus carrier that has a quality of immune response that is high enough to clear the virus from the blood. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">However, it is insufficient to remove its DNA from the bone marrow. The virus will eventually reactivate and trigger the symptoms.\u00a0<\/span><\/p>\n<h3 id='progressive-level'><span style=\"font-weight: 400;\">Progressive level<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Once the infection reaches the progressive level, cats carry the tiny virus pieces in the blood. They are highly contagious to other cats, with severe symptoms of secondary infections.<\/span><\/p>\n<h2 id='treatment-of-felv'><span style=\"font-weight: 400;\">Treatment of FeLV<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Unfortunately, there is no cure for FeLV. The current possibilities are limited to the prevention and treatment of minor FeLV-induced symptoms (for instance, a <\/span><span style=\"font-weight: 400;\">FeLV cat<\/span><span style=\"font-weight: 400;\"> will often get antibiotic prescriptions against bacterial infections or blood transfusions for alleviating the effects of anemia, etc.). <\/span><\/p>\n<p><span style=\"font-weight: 400;\">Still, there are certain things you should focus on.<\/span><\/p>\n<h3 id='attention-to-nutrition'><span style=\"font-weight: 400;\">Attention to nutrition<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Nutrition is vital when it comes to treating the symptoms. It is a good idea to supply your cat with some of the immuno-boosters available on the market (do ask your veterinarian to recommend the best one). <\/span><\/p>\n<p><span style=\"font-weight: 400;\">To treat <\/span><span style=\"font-weight: 400;\">feline leukemia in cats<\/span><span style=\"font-weight: 400;\">, you should give your cat the essential nutrients, vitamins, and enzymes in a tasty form.<\/span><\/p>\n<h3 id='foods-to-avoid'><span style=\"font-weight: 400;\">Foods to avoid<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">You should avoid feeding your cat meals that possibly contain bacteria, such as eggs and raw meat. Whenever you have some spare time, dedicate a little portion of it to preparing cooked meals for your cat \u2013 it will mean a lot.<\/span><\/p>\n<h3 id='hygiene'><span style=\"font-weight: 400;\">Hygiene<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">First of all, make sure that all the new cats you adopt have undergone a <\/span><span style=\"font-weight: 400;\">FeLV test<\/span><span style=\"font-weight: 400;\">. If you happen to have a cat with FeLV sharing the home with healthy cats,<\/span><a href=\"https:\/\/petpedia.co\/blog\/cat-care\"> <span style=\"font-weight: 400;\">take care of their bowls and litter box hygiene<\/span><\/a><span style=\"font-weight: 400;\">, and make sure that none of them are shared between the cats.<\/span><\/p>\n<h2 id='prevention'><span style=\"font-weight: 400;\">Prevention<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">FeLV is highly preventable, but not completely. The reason is obvious \u2013 one cannot control a cat completely. Still, there are certain measures a responsible owner should consider.<\/span><\/p>\n<h3 id='restricting-the-cat%e2%80%99s-exposure-to-felv'><span style=\"font-weight: 400;\">Restricting the cat\u2019s exposure to FeLV<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">FeLV transmission<\/span><span style=\"font-weight: 400;\"> is possible during each healthy cat\u2019s exposure to the potentially infected cats. With that said, make sure to keep your healthy cat away from the potentially infected cats. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">It is highly recommended that the infected cat be neutered and kept indoors. If access to the outside world is allowed (we admit, it is cruel to completely devoid a cat of the freedom to explore its environment), provide a space with a secure enclosure.<\/span><\/p>\n<h3 id='feline-leukemia-vaccine'><span style=\"font-weight: 400;\">Feline leukemia vaccine<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">FeLV vaccines have been available for many years and have dramatically decreased the incidence of FeLV. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">However, while they certainly are efficient for preventing the spread of\u00a0 FeLV and accordingly controlling the detrimental effects of it, they are not 100% reliable, as is the case with any other vaccine.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Still, the experts highly recommend the FeLV vaccination for all kittens. As for adult cats, you have to make a sensible decision based on their lifestyle and potential exposure to the virus.<\/span><\/p>\n<h2 id='potential-felv-vaccine-side-effects'><span style=\"font-weight: 400;\">Potential <\/span><span style=\"font-weight: 400;\">FeLV Vaccine Side Effects<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Minor allergic reactions to the vaccine are possible. FeLV vaccines have been formulated to be as harmless as possible. The side effects are highly unlikely (apart from mildly sluggish behavior immediately following the vaccination). <\/span><\/p>\n<p><span style=\"font-weight: 400;\">Since these usually happen immediately after the vaccination, a veterinarian will provide an efficient treatment right away.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The vaccine is being constantly improved upon so that the risks are minimized. However, if you still have concerns over it, you might want to discuss things in detail with your veterinarian.<\/span><\/p>\n<h2 id='prognosis'><span style=\"font-weight: 400;\">Prognosis<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">There are no rules when it comes to <\/span><span style=\"font-weight: 400;\">feline leukemia<\/span><span style=\"font-weight: 400;\"> and <\/span><span style=\"font-weight: 400;\">life expectancy<\/span><span style=\"font-weight: 400;\">. Once a cat reaches the final stage of FeLV, it is most likely to live up to several months if cared for properly.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Sometimes, a cat with FeLV will live for three to four years after being diagnosed with the virus. Statistics show that approximately 20% of cats with feline leukemia get to live over three years (though with an inevitably changed quality of life) after the diagnosis.<\/span><\/p>\n<h2 id='felv-vs-fiv'><span style=\"font-weight: 400;\">FeLV vs. FIV<\/span><\/h2>\n<ul>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Both FeLV and FIV belong to the same family of viruses, retroviruses. Still, FIV is a lentivirus, while FeLV is a gamma-retrovirus.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Both viruses are characterized by gradual progression, but FeLV will usually progress more quickly.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Both cause multiple secondary infections, but <\/span><span style=\"font-weight: 400;\">FeLV cats<\/span><span style=\"font-weight: 400;\"> usually suffer from more severe illnesses such as cancer.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">FeLV is transmitted during casual interaction between the cats. On the other hand, FIV has to enter another cat\u2019s bloodstream to be transmitted.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">While FeLV-positive cats must live in a single-cat household to prevent the spread, FIV cats can safely share a home with other cats.<\/span><\/li>\n<\/ul>\n<h2 id='faq'><span style=\"font-weight: 400;\">FAQ<\/span><\/h2>\n<h3 id='how-long-do-cats-with-felv-live'><span style=\"font-weight: 400;\">How long do cats with FeLV live?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">It depends on how well taken care of the cat is. Some cats get to live up to 15 years, like any other healthy cat. The life expectancy is heavily dependent on whether a cat gets infected as a kitten or as an adult. The virus is harsh on kittens, who mostly live up to 2 years.<\/span><\/p>\n<h3 id='should-a-cat-with-feline-leukemia-be-put-down'><span style=\"font-weight: 400;\">Should a cat with feline leukemia be put down?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">There is no need to get a cat euthanized because of the FeLV diagnosis. As long as your cat feels good, has an appetite, and has an overall sound quality of life, just keep doing whatever you can to prolong this, following the steps discussed in the treatment section.<\/span><\/p>\n<h3 id='how-do-you-treat-felv-in-cats'><span style=\"font-weight: 400;\">How do you treat FeLV in cats?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Unfortunately, there is no cure for FeLV at the moment. However, there is a lot that you can do. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">Regular veterinary care and undertaking the preventative measures that we\u2019ve mentioned in the prevention section will undoubtedly help your cat feel good most of the time and fight off secondary infections if any appear.<\/span><\/p>\n<h3 id='can-felv-positive-cats-live-with-other-cats'><span style=\"font-weight: 400;\">Can FeLV-positive cats live with other cats?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">No. Cats positive for FeLV virus actually require special treatment and environment. Other animals, such as bunnies or<\/span><a href=\"https:\/\/petpedia.co\/blog\/dog-statistics\/\"> <span style=\"font-weight: 400;\">family dogs<\/span><\/a><span style=\"font-weight: 400;\">, can share the same household with FeLV-infected cats safely. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">However, a cat with FeLV must not live with other felines that don\u2019t have the disease since the virus is spread easily via shared bowls, litter boxes, etc.<\/span><\/p>\n<h3 id='what-are-the-final-stages-of-feline-leukemia'><span style=\"font-weight: 400;\">What are the final stages of feline leukemia?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">There are no actual \u201cstages\u201d of FeLV. Still, we can roughly differentiate between the initial and final phases, the latter of which is characterized by more severe symptoms. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">As described in the progression section, once the disease reaches its final stage, apart from cats having severe symptoms, the infection becomes highly contagious.<\/span><\/p>\n<h3 id='what-is-the-life-expectancy-of-a-cat-with-fiv'><span style=\"font-weight: 400;\">What is the life expectancy of a cat with FIV?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Although FIV prognosis might be slightly better, the FIV-positive cats\u2019 life spans are dependent on how the owners take care of them (as of those with FeLV). Both cats with FIV and cats with FeLV are likely to die sooner than an uninfected cat would. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">As mentioned, a cat with FIV living up to 15 years is not an uncommon occurrence. Still, neither is a cat living for only five years after the diagnosis.\u00a0<\/span><\/p>\n<h3 id='do-indoor-cats-need-a-felv-vaccine'><span style=\"font-weight: 400;\">Do indoor cats need<\/span><span style=\"font-weight: 400;\"> a <\/span><span style=\"font-weight: 400;\">FeLV vaccine?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Not necessarily. The vaccine might not be beneficial at all for adult cats kept indoors. An owner should consult a vet to discuss the benefits and disadvantages of the vaccine based on its specific lifestyle, surroundings, and exposure to the virus.<\/span><\/p>\n<h3 id='can-feline-leukemia-be-transmitted-by-fleas'><span style=\"font-weight: 400;\">Can feline leukemia be transmitted by fleas?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">There haven\u2019t been reports of cat diseases being transmitted to felines by insects, including fleas. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">However, one of the older studies from 2003 examining the fleas that were fed for 24 hours with FeLV-infected blood has found that fleas might be potential carriers of the virus in vitro and possibly in vivo as well. However, we still lack modern-day evidence for the claim.<\/span><\/p>\n<h3 id='when-should-kittens-be-tested-for-felv'><span style=\"font-weight: 400;\">When should kittens be tested for FeLV?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Veterinarians say that there is no specific age at which kittens need to be tested for FIV and FeLV. Still, they should be tested in a timely manner when around six months old.

Some cats get to live up to 15 years, like any other healthy cat. The life expectancy is heavily dependent on whether a cat gets infected as a kitten or as an adult. The virus is harsh on kittens, who mostly live up to 2 years.\"}},{\"@type\":\"Question\",\"name\":\"Should a cat with feline leukemia be put down?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"There is no need to get a cat euthanized because of the FeLV diagnosis. As long as your cat feels good, has an appetite, and has an overall sound quality of life, just keep doing whatever you can to prolong this, following the steps discussed in the treatment section.\"}},{\"@type\":\"Question\",\"name\":\"How do you treat FeLV in cats?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Unfortunately, there is no cure for FeLV at the moment. However, there is a lot that you can do.\\n\\nRegular veterinary care and undertaking the preventative measures that we\u2019ve mentioned in the prevention section will undoubtedly help your cat feel good most of the time and fight off secondary infections if any appear.\"}},{\"@type\":\"Question\",\"name\":\"Can FeLV-positive cats live with other cats?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"No. Cats positive for FeLV virus actually require special treatment and environment. Other animals, such as bunnies or family dogs, can share the same household with FeLV-infected cats safely.\\n\\nHowever, a cat with FeLV must not live with other felines that don\u2019t have the disease since the virus is spread easily via shared bowls, litter boxes, etc.\"}},{\"@type\":\"Question\",\"name\":\"What are the final stages of feline leukemia?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"There are no actual \u201cstages\u201d of FeLV. Still, we can roughly differentiate between the initial and final phases, the latter of which is characterized by more severe symptoms.\\n\\nAs described in the progression section, once the disease reaches its final stage, apart from cats having severe symptoms, the infection becomes highly contagious.\"}},{\"@type\":\"Question\",\"name\":\"What is the life expectancy of a cat with FIV?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Although FIV prognosis might be slightly better, the FIV-positive cats\u2019 life spans are dependent on how the owners take care of them (as of those with FeLV). Both cats with FIV and cats with FeLV are likely to die sooner than an uninfected cat would.\\n\\nAs mentioned, a cat with FIV living up to 15 years is not an uncommon occurrence. Still, neither is a cat living for only five years after the diagnosis.\u00a0\"}},{\"@type\":\"Question\",\"name\":\"Do indoor cats need a FeLV vaccine?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Not necessarily. The vaccine might not be beneficial at all for adult cats kept indoors. An owner should consult a vet to discuss the benefits and disadvantages of the vaccine based on its specific lifestyle, surroundings, and exposure to the virus.\"}},{\"@type\":\"Question\",\"name\":\"Can feline leukemia be transmitted by fleas?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"There haven\u2019t been reports of cat diseases being transmitted to felines by insects, including fleas.\\n\\nHowever, one of the older studies from 2003 examining the fleas that were fed for 24 hours with FeLV-infected blood has found that fleas might be potential carriers of the virus in vitro and possibly in vivo as well. However, we still lack modern-day evidence for the claim.\"}},{\"@type\":\"Question\",\"name\":\"When should kittens be tested for FeLV?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Veterinarians say that there is no specific age at which kittens need to be tested for FIV and FeLV.
