This morning @ 8:45 am CST we took Rocky's BG at 461. I fed him half a can of 5.5 oz Friskies Prime Filets (not exactly low carb, maybe mid-carb?), which he ate all of and then ate one of the other cat's Friskies left overs. So he had quite a bit to eat. Half hour later I gave him the vet prescribed 3 units of Novolin Fast forward to 20 minutes ago, 1:22 pm (about 4 hours after his shoot) and I catch him eating some food from the dog bowl. He shouldn't be doing that. So we check him and his BG is 51. I don't notice any symptoms other than hunger. So I give him another half of 5.5 oz Friskies, which he annihilates. So I gave him some high-carb treats and some licks of cherry jam. He's sleeping contently in his favorite sun-spot in the kitchen right now I believe I've read 30 and below is hypo for a cat. Is 50 too low, too? The thing is I haven't figured out when his nadir is. From the data I have so far I thought it was 6 hours but 51 at +4 is the lowest he's ever gotten so far on a full stomach When should I test him again, and is the food stuff I just gave him sufficient to keep his BG from dropping further?
