My cat is two and a half years old. He is declawed and neutered. He has moved several times and was ENTIRELY okay with that. Since we moved in to the most recent house (9 months ago) and a permanent house ... he has began to spray in the house. He goes outside on and off and is liking that more than being inside. This may have something to do with it, I need to train him back to being a house cat like he was the first year and a half of his life. I am thinking about crating him to do so. Any suggestions?
