In side only.

Skinny was a stray. Neighbors around us looked after him (he was approx almost yr when we took him into house in Sept) by leaving stuff out for him but never took interest to take him in as their own. He is inside only and loves it.

Thumper, we got her from PetSmart adoption, she came to us declawed so she has always been inside kitty.

RB Butterscotch was apartment complex (where we first lived before buying our house) stray (owner left him) and he was outside for almost 1 yr before we took him in to our house and hearts. He was inside only kitty.
