Pets by the numbers

Understanding the Data

Obtaining accurate statistical data about pets in the United States isn’t easy. Most of the information is based on estimates derived from two periodic surveys, and the various survey takers do not agree. Data reflecting shelter/rescue animal populations is spotty due to a lack of reporting requirements, which leaders in animal welfare are aiming to address with the Shelter Animals Count project.

There are two main sources of pet demographics in the United States: the biennial APPA National Pet Owners Survey by the American Pet Products Association, and the U.S. Pet Ownership & Demographics Sourcebook by the American Veterinary Medical Association (AVMA) which is published every five years. These surveys provide data about trends in pet ownership and produce estimates of the total number of dogs and cats.

The following is select data from the APPA and the AVMA. For additional information—including questions about how to interpret this data—please reach out directly to the APPA and/or AVMA.

The Numbers

Pet Ownership Estimates from Underserved Communities

While the figures referenced previously tend to reflect mainstream America, the Pets for Life team of Humane World for Animals has spent years working in, and collecting data from, our nation’s most underserved communities which lack access to affordable and available pet resources. We have found startling differences in pet ownership. People living in underserved communities love their pets as much as pet owners anywhere else in the nation. However, there is extreme inequity in access to veterinary care, spay/neuter providers and other services most Americans take for granted, and this difference is reflected in the data:

• Pets living in underserved communities in the U.S.: 22 million
• Percentage of pets living in underserved communities who are not spayed or neutered: 88%
• Percentage of pets living in underserved communities who have never seen a veterinarian: 69%

Community Cat Estimates

Cats can be divided into three populations—those who are personal pets, those being cared for by shelters and rescues and those who live their lives out in our communities. Community cats are friendly stray or abandoned cats as well as feral (unsocialized) cats and cats who fall somewhere in between. These cats are unowned, but may be provided with food, water and/or shelter by caring individuals. The HSUS advocates for a trap-neuter-return approach to humanely managing community cats.

• Estimated number of community cats in the U.S.: 30 to 40 million [1]
• Percentage of community cats who are spayed/neutered: Unknown (this will vary by community based on implementation of community cat management strategies)
• Average number of litters produced by an intact female community cat: 1.4 litters/year [2]
• Mean number of kittens in each litter produced by intact community cats: 3 kittens/litter [2]
• Estimated survivorship of community kittens, 0-6 months: 25% [2]
• Estimated annual survivorship of adult community cats: 70% [3]
• Percentage of people who believe leaving a community cat outdoors is preferable to having him or her caught and euthanized: 81% [4]
• Percentage of people in the U.S. providing food for community cats: 10% of the general public and 17% of pet owners feed free-roaming cats. [5, 6]

Shelter & Rescue Group Estimates

Accurate data from shelters and rescue groups is difficult to obtain because there is no central data reporting system for these institutions, and many under-resourced shelters may not have the technology or ability to share their data nationally. Humane World for Animals is working with a wide variety of stakeholders to change this through Shelter Animals Count, an initiative formed in 2011 to create and share a national database of sheltered animal statistics, providing facts and enabling insights that will save lives and keep more pets with their families. In the meantime, here are the best estimates we've found:

• In some regions of the United States, 50-75% of the shelter population is cats, and cats and kittens are overwhelmingly more at risk for euthanasia.
• The number of cats and dogs entering shelters annually is down significantly from 20+ million in 1973. (Source: Dr. Andrew Rowan, Jan. 2019)
• The euthanasia of healthy, adoptable cats and dogs in U.S. shelters is down to its lowest point in history. While difficult to pinpoint an exact figure, best estimates are that fewer than 750,000 healthy and safe cats and dogs are euthanized annually. The remaining cats and dogs who are euthanized experience untreatable medical illnesses or are unsafe to place in the community.Estimated amount spent by humane organizations annually: $3 billion (about $10 per capita) (Source: Dr. Andrew Rowan, Jan. 2019)
• Estimated amount spent by animal control organizations annually: $800 million to $1 billion (about $34 per capita) (Dr. Andrew Rowan, Jan. 2019)
• Estimated number of brick-and-mortar animal shelters in the US: 4,404 (Source: Best Friends Animal Society)
