I have an adult male cat that has begun peeing on the dogâ€™s bed. I know itâ€™s not medical - he has been checked. I have the Catgenie litter box system so his litterbox is never dirty â€“ so this cannot be the issue. I am pretty sure he is not stressed. And he loves the dog, so I am not sure what his problem is. I am not sure what to do â€“ help me!
