"Thousands of years ago, cats were worshipped as gods. Cats have never forgotten this."

Animal protection advocates call attention to pet overpopulation in the United States. According to the Humane Society of the United States, 3-4 million dogs and cats are euthanized each year in the country and many more are confined to cages in shelters. This situation is created by nonneutered animals (spayed/castrated) reproducing and people intentionally breeding animals. A particularly problematic combination of economic hardship combined with a love of animals contributes to this problem in parts of the rural United States.[12] There are also major overpopulation problems with other pet species, such as birds and rabbits. Local humane societies, Societies for the Prevention of Cruelty to Animals (SPCAs), and other animal protection organizations urge people to neuter their pets and to adopt animals from animal shelters instead of purchasing them from breeders or pet stores.
