Caimans and small crocodilians are occasionally kept as exotic pets, but their welfare needs - space, temperature gradients, UV provision, and prey - are rarely met in domestic settings.
Caiman welfare in domestic settings is almost invariably compromised. These animals require large, complex enclosures with water of specific chemistry and temperature, deep UV-B provision, and whole prey feeding - requirements that few domestic keepers can meet for an animal that will live 30-40 years. Animals in inadequate conditions develop metabolic bone disease, skin problems, and chronic stress. Surrendered caimans are difficult to rehome because of their specialist needs and the small number of appropriate facilities. The welfare case against purchasing crocodilians as pets is overwhelming - even owners who begin with good intentions typically cannot maintain appropriate conditions as animals grow.
