His SDMA is normal which is a more reliable marker for kidney function. He may have been mildly dehydrated which can cause creatinine to elevate. Your vet could run a urinalysis to check his urine specific gravity and then recheck his BUN and Creatinine in 3 months to monitor for any increases.

Poor Robin Hood. Chances are that he doesn't have true kidney disease at his age. I would stop feeding the canned meat and try to just feed him cat food until his next recheck. If his values are still elevated at his next recheck, I would ask the vet about checking his urine specific gravity to see if the kidney elevations are from the kidneys themselves or some other cause. Also, with them just being right above normal, this could be his "normal" if he is a muscular cat. Your vet should also be able to sent off a test called an SDMA to help determine if this is truly kidney related. Finally, if they truly believe it is due to his kidneys, I would have an abdominal ultrasound done to see what his kidney look like. I would be worried that he may have polycystic kidney disease if he is showing signs of kidney disease at this young age. I know it is hard not to do but I wouldn't get too worked up quite yet. I think the values need to be recheck and more information needs to be gathered before we know for sure. I hope this helps!
