Diabetic cat with seizures.

Dr. Marie replied:

Oh dear, I am sorry to hear that you and Jasper are going through this.

There are many possible reasons for seizures. When an animal has a diabetic seizure it is because the glucose level has dropped too low. When we give insulin what happens is it lowers the blood sugar. If we lower it too much then an animal can seizure.

The seizures really can be at any time. We can't determine too much by the fact that they were hours apart.

It is very unusual for one unit of insulin to drop the blood sugar to the level to cause seizures. Has your vet mentioned a possibility that Jasper is not diabetic any more? Occasionally we can see a cat that recovers from diabetes and doesn't need insulin any more. You may want to ask your vet about this.

The next possibility for the seizures is an insulinoma. This is a tumor on the pancreas that secretes insulin. It can secrete it at random times which can cause the blood sugar to drop dramatically at any time resulting in seizures.

It's also possible that something else is going on to cause the seizures such as a brain tumor but this can be difficult to diagnose.

While I can't advise you on what to do with your cat's insulin you may want to ask your vet about trying Jasper without any insulin for a while to see how things go. You could also consider an ultrasound to look for a tumor on the pancreas. Sometimes they are obvious, but not always.

I hope everything is ok.

Dr. Marie.
