My cat is a 15 year old feline cat. He was just at the vet

Customer Question

My cat is a 15 year old feline cat. He was just at the vet last week for a check up and had blood work. Everything was fine except creatine up to 230 because he has been on high protein diet since March. I just noticed yesterday a canker like sore on one of his lower incisor teeth. Could this be caused by him being reintroduced to hard food this past week?

Hello & welcome, I am Dr. B, a licensed veterinarian and I would like to help you with your wee one today.

Now if he has a high creatinine, reducing the protein can help but you will want to also increase his fluid intake (offering water, cat milk, low protein canned foods, etc) since dehydration can also cause this. Otherwise, in regards ***** ***** question, it is quite possible that this is ulcer is due to mechanical irritation from the hard diet. Though we can also see this if he caught the gum when chewing. But in either case, that should heal and settle as he adjusts to the new diet. Of course, we need to tread with care, since we can see sores secondary to kidney issues (if his urea was also elevated) and also with dental disease or some of our cat viruses (herpes and calicivirus). So, you are fine to make those changes to try to improve his creatinine but we'd want to just monitor these and rule out those other concerns if it has not healed over this week or if we see any other lesions.

Kind regards,

Dr. B.
