I have a cat that is about 2 yaers old. He is very much an outside cat. Refuses to use a litter box and doesn't stay in very much at all is there some way to try to keep him in more and to make him a little more active while inside?
You can try buying indoor grass. It is real grass sold in a container and it is used for cats that would rather go to the bathroom outside. It also gives cats the feeling of being outside. Try scratch boards, cat toys etc.. This might make the inddor experience more exciting. Good luck, vetcare
