Fat Boy was diagnosed about April. He was in the 500's, now when I have checked periodically he's been in the 250/300 range, sometimes less etc..as I know stress and other things can factor. Tonight was a huge scare with a diabetic coma: He was just "out of it". Glassy eyes, unresponsive, purred, but wasn't there. Stiff, weak, just awful. Just terrifying. I did everything I had read to do: Corn syrup/honey..took longer than I thought to get him to snap out of it. It took him a while: he ate, and is now on my bed, calmly sleeping, but exhausted. I called my vet and he said to monitor him, and not to rush him anywhere because now that he's out of it, there's nothing to be done. And this type of behavior is normal. I know i sound like a hack, because everyone on here is so organized about everything..I travel for work, have 13 other cats, and a dog..so I am just trying to get Fat Boy healthy and organized. After a blood crash (assuming that is what it was based on the symptoms: too low of blood sugar), and after this type of thing..what can I expect behavior wise? He's passed out on the bed, is responsive when I pet him, but just acting tired..which he should right? After all his body just went through a train wreck. Any advice would be appreciated. I don't check his blood at home, but I am realizing I probably should. He's on Lantus 2x a day, 5 units.
