My siamse male cat had a block urine two years ago. I test his urine for PH balance often and his diet is
CD-S. He misses his cat treat. The vet said don't give him anything else but CDS food. There there some I can give for a treat.
I agree with your vet. Why do you want to cause problems? If he has been doing well on the cat food, then do not change anythng. A urinary blockage is very painful and could be deadly. vetcare
