I have two diabetics, one has done very well with his injections/eating, the other is just not doing well. She's lost weight, the rear legs just don't seem to work so well for her. They give out on her often. One leg was broken about 7 years ago, we saved the leg but had to put a rod in and have kept it in. She's always done well with it until the diabetes hit. I remembered my mom taking b-12 shots after giving birth to my twin brothers (they came in at 18 pounds), it did wonders for her and I'm thinking there should be something like that for my cat. What I came up with was Methylcobalamin. Anybody using it?
