Wild animal babies are attractive and lovable. We all adore an irresistibly cute and cuddly ocelot, bobcat, monkey, or a bear while a baby, but these babies grow up in no time and, if they are kept as pets, they become a nuisance and danger to themselves and to their surroundings.
Another point to consider is that care of wild animals eventually becomes very difficult, or better said, impossible. Their appropriate care demands the expertise of the species, tailor-made facilities, and indefatigable dedication lifelong. When the babies become older and are impossible to handle, they are usually put away or passed from owner to owner. Worse yet, wild animals that are declawed or changed in some way to fit into a home are not accepted into the zoos. So, at times, they are let loose in an environment where their survival is, at best, iffy. See the link wild life risk to check more about pets.
What is more, these animals are social creatures and they need and deserve the company of their own kind. Even when their physical health is taken care of, they grow up with behavior problems and act unpredictably because they are out of their natural environment.
Wild animals also may come with unknown viruses and make other pets and people in a household ill. For example, lizards are famous for carrying the salmonella virus as some primates are for Herpes B. Other animals may bring rabies or still unknown and undetected diseases, and if we can take these animals back to their initial environment, it is probable that they will transport diseases from domestic cats and dogs to the wild.
Nobody benefits from keeping wild animals as pets, except for their breeders and sellers who exploit wildlife for huge financial gains. These people take animal babies away from their mothers at too young an age and transport them under deplorable conditions to the markets to be sold as pets.
During the transportation, many of the babies die in outrageous numbers; 90% of the reptiles and 95% of the birds are dead, long before reaching their prospective owners. In addition, as the result of the wild animal trade, natural habitats are disturbed and quite a few species become extinct, as in the case of several West Indies species of Macaws.
Owning a wild animal is not a status symbol. The actress or singer with a python, boa, or an anaconda wrapped around her (or his) body is neither being adventurous nor sexy. Moreover, she is advertising to the entire world that her artistic talent amounts to zero and she can be sure that people who feel like I do will boycott her work as long as she stays in the public eye.
Sometimes wild animal merchants crossbreed wild and domestic species. This too is an appalling practice because it makes the animals inapt to survive both in the wild and in a household with other pets and young children.
