so i’ve been thinking of getting a cat, thing is i’m living inside of a small (not too small, great for a single person [me]) but i’m afraid the cat will be in a bad enviroment, this being a kinda small space where he can’t run or exercise or play outside or do regular cat stuff, so i eas wondering, is it bad for cats to live inside and never go out? i want 'em to have a good life
