What a scary event for you. I am happy to hear that Max is ok. I agree with your vet...he has a seizure disorder and that is why he had a seizure. I would not give another moment's thought about the food. We always want a reason for things; but sometimes the reason is simple. You have been a great mom to Max and had all the appropriate tests done and know that he has a seizure disorder...and you also know how to handle it. You done good, Mom.
