Well, I didn't see the last few suggestions until after I just gave him his PM shot..and I gave 2 units. He was 418 just now at his PMPS. I'm going to be reading more about the Lantus protocols, depots, etc. It's just very new to me, since he's only been on it a few weeks, compared to being on Vetsulin for the last year. So bear with me! As for feeding..I've tried the twice a day feeding..and he does gobble up 1 1/2 cans of FF at a time! Then I've also tried 1 can in the morning, 1/2 can at noon, 1 can for dinner, 1/2 can evening. It's usually 3-3 1/2 cans/day. He's still at 12.5 lbs so that's good (was 18 before dx!) I really do appreciate all your help! I couldn't have gone through today without all of you! When Tigger was less than one-year-old he was attacked by a coyote. Luckily my husband was on his way home from work at 6 AM, saw the coyote running across the street with Tigger in his mouth and he honked his horn, flashed his lights. The coyote dropped the cat and took off. Luckily Tigger lived through it with a few puncture wounds and a broken jaw. Aside from that issue, he's been perfectly healthy for the last 10 years, never a trip to the vet except for regular check ups. So all of this has really thrown me for a loop! But I figure he still has some good lives left in him!
