My name is Gravy!

This is the hardest thing we have had to do but we have had him for three years and he is just not happy with my dominant cat. He territorially marks. We had a urinalysis done on him and several other tests and it is purely behavioral. We have tried different medications, pheromones, and litters and nothing works. He needs to be an only cat or the dominant cat. He is such a sweet boy and is cuddly and sweet once he warms up. He is truly an amazing cat. He just needs a home that can accommodate him. His only other flaw is that he chews and consumes plastic.
