Previous Thread http://www.felinediabetes.com/FDMB/threads/tigers-tid-3x-a-day-vetsulin-ride.227584/#post-2550049 With advice from members I have put Tiger back on Prozinc at 11am(CST). His AMPS at 10:30am was HI. But that was expected he'd gone 8hrs without insulin. Gave him 5.5U after he ate whole can of Friskies. Tigers' Ride: Tried Prozinc when he was first diagnosed. His bg almost always read HI. Didn't help him at all..take a look see at Tiger's SS. Advice from Doc and members switched him to Vetsulin 2x a day. Vetsulin works fast, the downfall is it wore off at 8-9hrs after shot. So roughly 6hrs he'd go without insulin. Soo, we then tried him 3x a day(TID..see Tiger's TID SS) he did good on it. Unfortunately it has worn me and Tiger out. We are hoping that the Vetsulin kick started his body and he'll make a easy transition back to Prozinc.
