Kidney disease and seizures.

Species: Cat
Breed: None
Age: More than 15 ye
My cat is almost 18 years old and he has kidney disease. He is on a special diet my vet recommended. Last night he had a seizure for the second time, the first time was 6 weeks ago and I was hoping it was a fluke or something he ate. I read that kidney failure can produce seizures because of the build up of toxins in the blood. Is there any treatment to make sure he doesn't have another seizure, like seizure medications? Is the fact that he is starting to have seizures a bad sign? Will he start to have them more frequently. He is still moderately active and have a voracious appetite.

Dr. Marie replied:

Oh, I am sorry to hear that Misha is having these problems.

There are a few possible reasons for seizures. It is true that in the advanced stages of kidney disease there can be a buildup of toxins and this can cause seizures. Usually cats that are in stage are quite sick because of the kidney disease. They are usually very thin and have a poor appetite.

I get worried when an older animal who has no history of seizures starts having seizures. One of the more common reasons for an 18 year old animal to have seizures is a brain tumor. Unfortunately there is not a lot that can be done for a brain tumor.

It would be a great idea to have your vet do a blood panel on Misha to see if there is a medical reason for the seizures. Unfortunately if there isn't then a tumor is very likely.

In either case, it is possible that a medication such as phenobarbital can help to reduce the frequency of seizures.

I have seen some animals that who randomly have a seizure and then never have another so hopefully this is the case.

Dr. Marie.
