Susan called and said although she had no problem getting him to the vet. His blood sugar was actually fine, although they said that his claws are starting to come out because of the diabetes and he may or may not have kidney or liver damage. They were about to send him home with some antibiotics when he had two seizures. Now they're keeping him overnight because they don't know why he had them.
Mom's freaking out, but I keep telling her to stop jumping too far ahead and let's wait to see what the vet says. She's also concerned this is going to cost a lot of money, but I'm going to wait and see what happens before making any decisions.
