Smelly Urine Question

In the last couple of week's one of my male cat's urine has become very strong,he is 6 years old ,fixed at 4 years,I did change from feeding them Frickies to a high protion Walmart food. Could it be the food,he has no other problem's ie: going outside the box,spaying,able to go,just strong.Any idea's?

I would suggest getting a urinalysis done, in case he has an infection or other problem. Smell can sometimes be an indication of health problems. Your vet could possibly also think a different food may be better suited to him.

Yep I agrees Sherral, even if he does not appear sick, he might be. I would run him in for a check-up.
