Yes, I agree with Purrley...let us know how the vet appointment goes! I can imagine how scary that is!! The unfortunate thing is there are a multitude of reasons that could cause a seizure. Unfortunately a seizure is what killed one of my childhood cats. To this day we don't know what happened. He seized one day...and that was it! We just couldn't believe it!! It can be a UTI related event or something else, but I'm sure the vet will be able to help you. Keep an eye on your baby and please keep us posted!! Lots of hugs and scritches and love to you and your baby.
