Tyler was recently increased from 3 units of vetsulin to 4. He usually eats about 4 3oz cans of fancy feast a day. Typically, he has his breakfast and shot and then goes to sleep for a few hours. But, about 4 hours later the begging begins and doesn't really stop until about 3 hours before his second shot. He naps a little but if you go anywhere near his bowl he starts begging. I spoke with my vet who suggested I increase to 5 units in the morning but stay at 4 in the evening until we can do another fructosamine test. My biggest issue is that hunger and restlessness are signs of hypoglycemia but also seem to be signs of not enough insulin. So, how do I know which symptoms he is showing?
