we adopted a stray young male cat last winter during the bitter cold. He always insisted on going outside to 'do his business' and did not have a litter box. This year he is older and due to his fighting and getting nasty injuries, we felt it would be better for him to stay inside to recouperate. We set up a litter box.It took a few days for him to finally decide it was okay for him to use. However, he would hide in the corner after using it the first few days although we would give him a treat and tell him he was a good boy. I always accompanied him to the box (figuring it would be until Buddy got used to it and then he could go on his own). We had him neutered. During the night, he uses the box because we close the basement door because he will wake us up with his howling until we walk him to the litter. However, when we are up, he kicks up a fuss to go outside (which because of his injuries and the fact he wants to stay out and get beat up by the bully cat, we won't do) he won't use it unless we walk him downstairs all the way to the end of the basement to his box and stay there until he has finished. He does not urinate anywhere, he just holds it until we walk him to the litter box.
