Cats are good hunters, and you could call them fairly self-reliant animals. This makes them well suited for living outdoors. But outdoor cats should not have their claws trimmed or removed in case they need them for defense in a fight. Outside cats are also more susceptible to contagious feline diseases such as Feline Aids and the feline leukemia virus.
Cats do very well indoors.
If you choose to keep your cat indoors, you will find cats are good roommates. Cats are king of their domains. They will learn ever nook and cranny of a home, and make it their own. Cats are territorial. Don't be surprised if you're cat is intimidated by guests.
