My Morgan had diabetes. At first, I was overwhelmed. Partly because I had just had to say goodbye to a kitty with congestive heart failure. Morgan started with 10 units once a day and then went to 5 units twice a day. I changed his diet and for awhile he was on Purina DM and then I switched him to a grain free cat food. He'd also get a spoonful of canned food before he got his shots. If I forgot, he'd come and get me. He really wanted that canned food and didn't mind his shots at all. But with the change in diet and being very strict about what he ate, I was actually able to ween him off of the insulin completely. It took about 6 months though. We'd get his blood checked every 2 weeks and the vet kept reducing his insulin by 1 unit for each dosage. I know that is not the normal thing that happens, but it can. We were proof of that. But the main point of sharing this was to let you know that while it is stressful and overwhelming at the beginning, it is very manageable and we usually have more problem accepting it than our furkid. Make sure you have some Karo syrup on hand though just in case.
