Yes. Cats are domestic creatures, bred for a life in the home, and while many of them can survive on their own in the wild, their lives as a result are "nasty, brutish, and short," as they do not get the medical care they need. Additionally, these days few kittens are taught the skills they need to survive in the wild by their mothers, because we dislike the idea of our cats hunting and killing smaller animals, and so prevent the mothers from bringing home the animals she needs to teach these skills.
