Pet Adoption Statistics

Report Highlights. Research from the data science team at SparkysSpots.com revealed the following statistics about the current state of animal shelters in the United States in 2020.

  • Americans adopt roughly 3.2 million pets from shelters each year.
  • Shelters still contribute less than one-third of all pet adoptions.
  • Currently, about 67% of American households include at least one pet.

  • On average, adoption is significantly less expensive than buying an animal.

Adoption from Shelters

Pets adopted from shelters are often referred to as “rescues.” Shelters take in homeless animals and take care of their medical needs, including vaccinations and spay/neuter procedures. Shelter space is limited, however, and many animals must be euthanized due to overcrowding. Pet adoption saves lives, costs less, and ensures the animal you take home is healthy.

  • Nationwide, shelters take in more than 6 million animals each year.
  • 49% of all shelter animals are adopted.
  • Cats and dogs are adopted in equal numbers.
  • About 30% of all pets are adopted from shelters.
  • At least 50% of unadopted animals are euthanized.
  • Cats have the highest rate of euthanasia at 70%.
  • On average, the initial cost of pet adoption ranges from $370–$1020; very small animals like fish and hermit crabs can be as low as $9.
  • Clinics that specialize in spay/neuter procedures are consistently less expensive than regular veterinarians.
  • Some shelters offer discount pet insurance or veterinary services.
  • The average cost of adopting a dog is less than one-third what it would cost to purchase that same animal from a breeder.

Purebreds in Shelters

There’s no need to go to a breeder to get a purebred animal. Shelters often have a significant percentage of purebreds. There are even rescues that specialize in purebred animals. The Specialty Purebread Cat Rescue system, for example, has shelters throughout the Midwest.

  • 25% of dogs in shelters are purebred.
  • 4 of the 10 most popular dog breeds are also among the most common shelter dogs.
  • Some purebreds are high-risk for euthanasia.
    • Pit bulls are the most-surrendered, least-adopted breed.
    • 93% of pit bulls in shelters are ultimately euthanized.
    • Some “manmade” cat breeds cannot survive without human care.

Health Benefits of Pet Adoption

For most people, adopting an animal is about more than getting a pet. Studies show pets become important members of the household, providing comfort and companionship. Many children with autism and ADHD reportedly thrive working with therapy animals. Pets ease loneliness, increase sociability, and diminish stress.

  • Clinical tests show that pets:
    • Decrease blood pressure.
    • Decrease cholesterol levels.
    • Decrease triglyceride levels.
  • People who live alone decrease their risk of heart disease by 36% when they adopt a pet.
  • Animals boost human activity through exercise and play.
  • Dog owners are much more likely to get 90 minutes of daily exercise than those without dogs.
  • 87% of cat owners say their pets are good for their well-being.
  • 76% report their cat helps them cope with everyday life.

  • Babies living with pets develop more robust immune systems than those who don’t.

Communal Adoption

Sometimes homeless animals are adopted by a small community, such as neighbors in an apartment complex. These adoptions typically involve cats and are unofficial, beginning with one or more community members feeding a friendly stray. Neighbors may also take the cat to a local vet or let it indoors in bad weather.

  • 35 million community cats are estimated to live in the U.S.
  • Only 2% of community cats have been spayed or neutered.
  • 80% of new kittens are born to community cats.

  • 11% of community members provide the bulk of the cats’ food.

Community Benefits of Animal Adoption

By some estimates, over a hundred million animals live on the street. Most of these animals have not been sterilized, producing still more animals to roam city streets and neighborhoods. These animals can quickly overrun these areas, causing damage to both property and the local environment. Many strays are lost pets lacking ID.

  • Shelters report that fewer than 10% of intake animals are spayed or neutered.
  • Realistically, one female cat produces 3,200 decendents over 12 years.
  • Theoretically, one female cat could produce up to 420,000 descendents over 7 years.
  • Likewise, one unspayed dog could theoretically produce up to 67,000 descendents over 6 years.
  • Unneutered male cats are particularly aggressive and territorial, using excessive urine to mark a perimeter.
  • Ecologists consider loose feral cats extremely detrimental to their local environment.
