If I may offer.....start with a kitten because some older cats simply will NOT decide to live inside if they've already lived outside......had one buggar that destroyed not only the carpet in front of the door trying to get out but also ripped apart every window screen in his search for escape. Never went anywhere......just wouldn't be held back.

A kitten raised inside will be very comfortable and happy inside. It's a safer, better life for them as well......no getting attacked by dogs, hit by a car, etc etc etc.....

Get one! You'll love it!
