One of my older cats has a huge spraying problem. He will spray the stove knobs, the TV, cabinets, couches, outlets, etc. If we catch him and squirt him with water he will run away, only to spray a few hours later. The whole house smells like urine and its disgusting- we can barely have guests over. His spraying began about the time he was diagnosed with an overactive thyroid, but he is being treated for that and is better. We took him to the vet when this began, but the vet ruled out UTI, bladder infection, etc. What can I do to stop this? Could this be a sign of kidney problems? He is 13.
Thank you
