How Many Animal Shelters Are in the US Today?
Nonprofit rescue organizations and animal shelters care for abandoned, abused, and neglected animals. There are two types of animal shelters: municipal (kill) and no-kill shelters.
But, are there enough shelters in the US to take care of every poor abandoned soul?
1. There are 3,500 animal shelters in the US.
How many kill shelters are in the US? Too many!
Municipal shelters are also known as kill shelters. They are brick-and-mortar institutions that take in strays and abandoned pets. When a shelter is full, or its animals are old and sick, it’s policy to euthanize the animals.
2. Altogether, there are around 14,000 shelters and rescue groups in the US.
No-kill shelters and non profit rescue organizations also operate in the US, in addition to kill shelters. They rely on donations and staff to keep going, unlike the government-funded municipal shelters.
No-Kill Animal Shelter Statistics
No-kill shelters try to save every animal, heal them, and treat any behavioral issues they may have. These shelters focus on safety and high-quality of life.
3. No-kill shelters attempt to save 9 out of 10 animals.
In no-kill shelters, 90% of the animals brought in are adopted or rehomed. But, this doesn’t mean that these institutions do not apply euthanasia. There is still a 10% margin in which elderly and sick pets can be put down.
4. No-kill shelters can become overcrowded.
As a result of the 90% benchmark, many no-kill shelters turn away unwanted pets, as cats and dog shelter statistics show.
5. There are over 4,000 no-kill communities in America.
Even a no-kill community sometimes euthanizes animals. However, they can maintain their “no-kill” status as long as they achieve a save rate of at least 90%.
6. In 1994, San Francisco became the first no-kill city.
(Best Friends Animal Society)
Rich Avanzino was considered the father of the no-kill movement. Animal shelters facts point out that he established an adoption pact with the San Francisco Animal Care & Control. This made San Francisco the first no-kill city in the US.
7. Delaware became the first no-kill state in 2019.
Delaware has a save rate of 92.9%. This means that around 12,000 of the 13,000 pets in shelters were returned to their owners or adopted. So far, Delaware is the first and only no-kill state in the US.
8. On average, the US saves 76.6% of shelter animals.
Texas and California have the lowest save rates. According to the animal euthanasia statistics, in both these states, less than 75% of shelter animals are rehomed.
9. The goal of animal activists is to make the US a no-kill zone by 2025.
Even though it might seem a bit challenging, animal lovers believe that it can be done. So far, the number of euthanized animals keeps going down, and the number of rehomed pets is increasing.
How Many Dogs are in Shelters?
Even though the number of dogs in shelters has declined, there are still too many abandoned pups. Let’s see the precise numbers.
10. More than 6 million pets enter animal shelters across the US every year.
Animal shelter statistics from 2020 show that there are about 70 million stray animals on the US streets at any given time.
Only 10% of them (a bit more than 6 million) enter the shelters. The rest lives on the street — freezing during the winter and suffering from heat exhaustion during the summer.
11. The number of pets in shelters is declining.
2011 was one of the worst years for pets in shelters. There were 7.2 million pets taken in by animal shelters in the US.
Thanks to adoption and rehoming, that number has declined by over a million by 2019, as shelter animal statistics reveal.
12. Only 10% of the animals going into shelters are neutered.
(DoSomething, One Green Planet)
The low number of spayed or neutered animals could lead to “overpopulation,” and thus, an even greater number of euthanized animals.
Shelter dog statistics estimate that an unspayed dog and her puppies can produce 67,000 dogs in just six years if left unchecked. One female cat that hasn’t been spayed, along with her offspring, can create 420,000 cats in seven years.
13. A quarter of the dogs abandoned in shelters are purebred, Humane Society statistics reveal.
(DoSomething, One Green Planet, Humane Society)
Almost 25% of the dogs that enter local animal shelters have a documented pedigree. Most of the purebred dogs in shelters are pit bulls. Sadly, they’re among the least wanted dogs in the US.
Homeless Animal Statistics: How Many Pets Leave Animal Shelters?
The stigma surrounding shelter animals has been lifted over the years, and people tend to adopt instead of shop for a pet. But, sadly, not all homeless animals get adopted.
14. 710,000 strays are returned to their owners each year.
Out of all the strays that enter US animal shelters, 620,000 dogs are returned to their owners. And 90,000 cats are reunited with their owners, as the stray animal statistics show.
15. Microchipping increases return rates.
Cats that are microchipped are 20 times more likely to be returned to their owners. Dogs that had a microchip are 2.5 times more likely to get reunited with their owners than other strays in the shelter.
16. Approximately 1.6 million dogs are adopted from shelters every year.
Another 1.6 million cats are adopted from animal shelters each year, making the total number of adopted pets reach 3.2 million.
So, what percentage of pets are adopted? The history shows that of the 6.5 million cats and dogs brought into shelters, just under 50% get adopted.
The good news is that the adoption rates are increasing. However, there’s still much to be done to reduce the number of animals in shelters.
17. Dog adoptions soared to 10–13 a day during the Covid-19 pandemic.
(The Washington Post)
According to pet adoption statistics, the Society for the Prevention of Cruelty to Animals Los Angeles, recorded new records. The nonprofit shelter recorded double numbers of adoption compared to the previous year.
The Animal Care Centers of NYC also reports good news. 25% of people who have taken in foster dogs during the pandemic have adopted them, shaping the history of animal shelters.
18. The number of adopted shelter cats is practically standing still, as animal shelter trends show.
Shelters took in over 900,000 cats during 2020. The great majority of them were stray cats. However, their number is gradually decreasing, according to the Shelter Animals Count (SAC) data.
The number of adopted cats was on the rise up until the Covid-19 pandemic struck.
19. Under 1% of the animals in shelters are irremediably suffering.
(No Kill Advocacy Center)
Irremediable suffering refers to animals who have low chances of living without severe pain or urgent medical attention. This means that 99% of pets in shelters are healthy and adoptable.
20. Due to the Covid-19 pandemic, pet adoptions have decreased by 36% during 2020.
Even though dog adoptions are on the rise, the pandemic has affected the overall pet adoptions. The adoptions have slowed down, causing a significant drop in the adoption rates.
What Percentage of Animals are Killed in Shelters?
Unfortunately, many abandoned animals don’t live to see old age. Many of them are killed due to the lack of shelter space, animals’ poor health, or to protect other animals’ safety and health.
21. 625,000 pets were euthanized in 2019.
(Best Friends Animal Society)
It’s a fact that this number is incredibly high. It’s actually the second consecutive year recorded that the total number of dogs and cats killed in US animal shelters dropped to under one million, according to the animal euthanasia facts.
22. 17 million shelter animals were killed in America in 1984.
(Best Friends Animal Society)
This shockingly large number prompted animal activists to take charge and initiate the no-kill movement across the US.
23. Animal shelter facts and statistics reveal that PETA euthanized 1,614 animals in 2019.
Even PETA euthanizes animals. They claim they do so to relieve the animals of suffering, illness, and pain. Even though they help many animals, they still kill a substantial number of them.
24. More cats are killed than dogs.
(American Humane, Best Friends Animal Society)
About 625,000 cats and dogs entered US shelters in 2019. More dogs enter shelters, but more cats are killed. Approximately 70% of all killed animals were cats.
The majority of cats that enter shelters don’t have owner identification and thus are less likely to be returned to their owners.
25. Euthanasia means “good death.”
How do animal shelters euthanize animals? Proper euthanasia is done through intravenous injection of sodium pentobarbital, which is quick and painless.
26. Some shelters use inhumane methods to euthanize animals.
The sad truth is that many animal shelters still use decompression or gas chambers. This method not only euthanizes animals in an inhumane manner, but it also allows other animals to watch them suffer.
Some municipal officers euthanize pets with gunshots to the head, which is even more upsetting. This isn’t always immediately effective and causes even more pain and suffering to the pet, as the animal shelter euthanasia facts indicate.
27. Animal activists are trying to put an end to inhumane euthanasia.
Since 2013, around 70 shelters in 13 US states have chosen to shut down their gas chambers. There are currently 27 states that entirely ban the use of these chambers on pets, while four still use gas to euthanize shelter animals.
The end goal is to pass a ban on gas chambers in all 50 states.
28. The main reason for euthanasia is overpopulation.
Why do animal shelters kill animals? The answer is overcrowding, meaning that there are too many animals for shelters to take in.
Other reasons for euthanasia include elderly or sick animals. When an animal becomes ill, animal shelters euthanize the animal to stop the disease from spreading. Often when an animal is ill and in pain, the humane choice is to end its suffering.
29. 5 states account for 50% of shelter animals being killed in America.
(Today, Best Friends Animal Society)
And, according to the cat and dog euthanasia rates by state, almost all are in the South.
Texas tops the list with around 125,000 animals killed in shelters. California is second with 110,000, followed by Florida with 66,000, and North Carolina with 62,000 euthanized animals.
According to the Georgia animal shelter statistics, the state follows with 43,000 killed shelter animals round out the five states.
30. Three out of four Americans are against euthanizing animals.
(No Kill Advocacy Center)
Around 75% of Americans believe that it shouldn’t be legal to kill an animal if it’s healthy or can be treated by a vet. According to animal shelter facts and surveys, as many as 96% of US citizens believe humans are morally obliged to protect animals.
Abandoned Pets Facts: Why Do People Leave Their Pets in Animal Shelters?
Sometimes life happens. People get sick, get into debt, or move to the other side of the world and can’t take care of their pets. Of course, sometimes people abandon their pets for selfish reasons. Here are some of the most common ones.
31. About 30% of the animals in shelters are left there by their owners.
(Animal Foundation Platform)
Just for comparison, 42.5% of the animals in US shelters are impounded by animal control. Even though animal control takes in more strays, the percentage of abandoned pets is still pretty high.
32. Problems with the pet are the primary reason people abandon their animals.
So, how many animals are abandoned each year?
Looking at the stats, almost 47% of rehomed dogs and 42% of rehomed cats are abandoned by owners due to pet problems.
Pet problems include aggressive behavior, animals growing larger than expected, and health issues the owners couldn’t deal with.
33. Moving to a new place is why 8% of owners leave their pets.
Other causes for people abandoning their pets include living in a no-pet zone, incompatibility with other pets, and expenses.
About a third of the US is allergic to cats and dogs. Some 4% of cat and dog owners said they abandoned their animal companion due to personal problems, as animal shelter stats indicate.
Surprisingly, 11% of cat owners said they left their pet because they had too many household animals.
34. Most of the pets in shelters had been owned for less than one year.
Around 37.1% of dogs and 30% of cats were kept up to a year in shelters before being relinquished by their owners.
35. Pets from friends are the most likely to be abandoned.
Animal shelters statistics reveal that 32% of dogs and 33.2% of cats left in shelters were present from a friend. Gifted pets account for the largest number of relinquished companion animals.
36. Only 20% of people return an animal to a shelter.
(Animal Foundation Platform)
Around a fifth of the people who adopted a pet from an animal shelter end up taking it back.
Animal Shelter Funding Statistics
Taking care of millions of abandoned animals requires extensive funds. They’re typically collected by donations and funded by the government.
37. Animal shelters cost US citizens up to $2 billion every year.
(One Green Planet, PetMD)
The total cost of animals picked up by animal control and their sheltering, euthanasia, or disposal ranges between $1 to $2 billion annually.
Government funding for animal shelters is how most shelters get their funds. However, shelters also raise money through crowdfunding, fundraising events, and donations.
38. Not all animal organizations need donations.
One of those organizations is the American Society for the Prevention of Cruelty to Animals (ASPCA). Their 2019 total registered revenue counted $271,999,050, according to the animal shelter statistics from 2020.
39. Maddie’s Fund alone has donated over $237.6 million in grants.
Maddie’s Fund is one of the leading animal rights foundations. They’ve made numerous donations toward community lifesaving, medical education, foster care, etc.
40. Why are there so many stray cats?
Overpopulation is the number one reason for stray or abandoned animals—only 2% of stray cats are neutered or spayed. Public opinion also plays a role. 81% of Americans think that leaving a cat outside is better than having it euthanized.
41. How many animals are abused each year?
It’s estimated that around one million animals are abused every year. 250,000 alone are victims of animal hoarding.
Animal abuse statistics report that there’s a close relationship between animal and domestic violence. 71% of domestic violence survivors reported that their abuser had also injured, killed, or threatened to kill the household pet.
42. Do animal shelters need volunteers?
Volunteers are always needed, especially in nonprofit rescue organizations. If you’re 16 or over and wondering how to help animal shelters, volunteering is always a good idea.
Bear in mind that volunteers at no-kill shelters and rescue groups work for free. Unlike the workers in government-funded animal shelters who make about $35K a year.
The jobs they’re given range from walking dogs, feeding and cleaning cages to offering adoption counseling, and doing administrative chores.
Animal shelters also need pet foster parents to look after the animals. The animal usually stays with a foster parent for a few weeks to a couple months.
43. How long do animals stay in shelters before being put down?
As a rule, animal shelters wait at least 72 hours from when an animal is brought in before euthanizing it.
44. How many animals die in shelters each year?
For dogs, pit bulls take the lead. Almost 93% of the pit bulls that enter animal shelters are killed. They’re also the hardest to find homes for, as only one in 600 pit bulls will be adopted.
For cats, it’s the color, not the breed. Black cats have the highest euthanasia rate and are the least likely to be rehomed.
The Bottom Line
Why are animal shelters important? Animal shelters care for homeless or abandoned animals and try to give them a home or a humane death if there’s a need for it. Without them, there would be countless animals on the street.
However, not all animal shelters care for pets as they should. Many of these animals end up being euthanized or abused.
The primary way to help animals and animal shelters, for that matter, is to spay or neuter your pets. As the animal shelter statistics for 2021 indicate, it’s the best way to reduce the number of abandoned and euthanized animals.
