My cat was diagnosed in June. We've steadily been increasing the Vetsulin. We are now up to 5 units 2x a day. In addition, he takes a twice daily pill for hyperthyroidism (edited). We do not have a home monitoring system, and our vet discourages it. We have to bring him in every few weeks to see how he is doing. He's clearly not doing well. He drinks a lot of water and pee's all over the floor. We use dog training pads. I'm rethinking monitoring, because it looks like there can be spikes and dips that might be useful to know about. Vet has suggested there may be another form of insulin for him, but I'd hate to switch and have to go through months of trying to find the right dose. Anyway, I'm looking for whatever advice there might be. I'd really like the peeing all over the floor to stop.
