Cats are typically self-sufficient and thus do not need a lot of training. It is unfortunate, though, that some kittens can form bad habits as they mature. Such bad habits are common in cats that have been adopted, neglected, abused, taken in as a stray, or even purchased from a breeder. Even then, though, it seems that cats have a natural instinct guiding them to the litter box and thus a majority of them do not require “potty training.”
