There are several factors that can affect a cat's level of independence. Genetics can play a role, as some cats may be more genetically predisposed to be independent than others. A cat's environment can also be a factor, as cats that are raised in an environment where they are given more freedom may be more independent than cats that are kept in a more restrictive environment. Finally, cats may learn to be more independent through experience, as cats that are allowed to explore and interact with the world around them may become more independent than cats that are kept in a confined space.
