Facts about U.S. Animal Shelters (source: ASPCA.ORG)
Currently, no government institution or animal organization is responsible for tabulating national statistics for the animal protection movement. These are national estimates; the figures may vary from state to state.
Approximately 6.5 million companion animals enter U.S. animal shelters nationwide every year. Of those, approximately 3.3 million are dogs and 3.2 million are cats. We estimate that the number of dogs and cats entering U.S. shelters annually has declined from approximately 7.2 million in 2011. The biggest decline was in dogs (from 3.9 million to 3.3 million).
Approximately 3.2 million shelter animals are adopted each year (1.6 million dogs and 1.6 million cats).
About 710,000 animals who enter shelters as strays are returned to their owners. Of those, 620,000 are dogs and only 90,000 are cats.
