A quick history first. Noah is a neutered male about 14 years old. He has cardiomyopathy and an enlarged heart that has broken through his cardiac sac. This has been confirmed by X-ray and two ultrasounds, one performed by a cardiac specialist. He also needs all his teeth pulled but only has a 10% chance of surviving the surgery so we control his pain with transdermal BUPE. He is also more than just nervous. He's never been crated, afraid of windows and any trip to the vet is emergency only. He is on U40 Caninsulin and is/was a high-dose bouncer. For the past month his numbers and dose have been going down about 5% / day to the point where I've reduced his dose to as little as 1 unit both AM and PM. I have not checked his weight but he is as chunky as ever and although he is a secret eater his appetite appears normal. The only drawback is that I have to pull him from his basket and show him his dish. His vision is fine, he just doesn't like eating when the other 5 cats are in the room. I also stimulate his appetite with Temptation treats, something I know is not good for his blood sugar but it gets him to eat every time. He never vomits and his stool is always normal. So the question is this. I know cats don't just suddenly go OTJ but is this typical of what happens? A slow and steady reduction in numbers? For us OTJ is something that happens to other cats and not here. It's almost like watching a miracle unfold before our eyes. Is it also more unlikely to happen given his age? He has gone as high as 6 units but that's usually when I know he's bouncing.
