Animal autopsy's cost to much money... We can't afford to do all that. We will take our surviving cat to the vet tomorrow though. Get him checked for heart worms and all that. We are thinking it could have been a heart worm or more likely just a heart condition. I checked all their food and treats too, but none of them have wheat gluton as an ingredient (which has been blamed for many pets deaths in the food recall.)

You just reminded me to check the recall list again though.
