If I had a cat, mine would be an indoor cat!
Feral cats are difficult to keep indoors. After being outside they get bored. I’ve had 2 exceptions, Chloe and Nimh. I caught Chloe when she was 2 years. She’d never been touched by a human. Warmth and food did it. She never asked to go out. Not once. Nimh went in and out until we moved here. I never let him out again. He’d ask once in awhile but I wouldn’t let him.
