Hi there. My furkid Tinker is 10. He was diagnosed last week. My vet basically said to give him 2 units of Lantus every 12 hours and change him to Purina DM. Which freaked me out but I bought the pen and the needles and watched a video and thought, ok I can do this. Then, being a good kitty mom I start reading on the interwebs and I find this site which says I need to test his Bg multiple times a day? And do curves, and worry about his levels and dips and timing of his snacks??? Which brings up several questions: 1. Why didn't my vet tell me all this? 2. Do I really have to do all this? I mean why is all this testing so important? 3. Are you kidding me?!?!? Sorry but I think I am in denial here. Help!!! P.s. He has been on insulin for about 3 days and is still drinking a lot.
