So for about a week my cat has been much improved. His eyes are back to normal. But the other day he did start limping. But it only lasted a short while. It was in response to him squeezing under the bed due to thunderstorms. That isn't a usual occurrence.

It seems the medicine for his limping can cause his immune system to slip.

So, I think I am going to give him the medicine for his limping as little as possible. Every three days and also give him the immunity support supplement. If the medicine for the limping doesn't improve things or makes him worse I will discontinue.

I don't think I will be taking him to the vet. Though I would love to know if he is sick, now that I know he has no kidney or diabetes... those are the big worries.
