we have a male cat who is just over a year old, recently we have been having issues keeping him in the house. now though he has lost a lot of weight and looks shaggy, when he uses the litter box it smells like he has sprayed its a horrible strong smell that will drop you to your knees. other then that hes just like a normal cat. we are worried that there is something wrong with him and was wondering if you could give us any insight on whats wrong with him and if he can spread it to the other cats we have. thank you candace and melissa
