The current theory on the seizure is caused (indirectly) by the new diabetic cat maintenance food that the vet put him on last week. It may have stabilized his blood glucose level to the point that he either doesn’t need his 2x daily insulin shots anymore, or we may need to adjust the amount that we give him. In any case, he’s cuddled up against Rosie Toes now and purring.
