I too have had an experience with this, at least my vet says this it what is was. Garbonzo Bean is a Birman and 6-8months ago had a seizure of some kind.... the vet thinks it was Feline Dilated Cardiomyopathy but can't really explain why. It's not Bonzo's diet. Anyway- they had us give him a baby asprin once a day for a week under the VET'S Care (as it IS/CAN be toxic to kitties) and other than having amuch bolder catatude now he seems to be fine and we look at EVERY day as a gift. So, sorry about Bill.
