I have a room my three cats stay in at night and during the day. They are no longer kittens. They have a big cat post with hole and shelves. Everything is out of their reach, other than what is for them. Before I had them in ex-large dog cages with litter box, food and water and shelf for them to lay on. I try to make things easier for myself and I don't want my house torn up. They are declawed - all four feet.
