In 2023, about 66% of U.S. households (86.9 million homes) owned pets, with dogs leading at 65.1 million households and cats at 46.5 million, according to the American Pet Products Association. Beyond these, rabbits, hamsters, and birds like budgerigars remain popular, especially in urban homes where space is limited.
Exotic pets have surged, with 13.6 million U.S. households owning reptiles (e.g., bearded dragons), small mammals (e.g., ferrets), or amphibians by 2022. In Europe, tropical fish dominate, with over 10 million aquariums maintained, reflecting a trend toward low-maintenance companions.
