We had a cat that became diabetic as a kitten.
He went into remission for three years then back to diabetes.
I gave him 10,000+ insulin injections.
Still miss the little bugger.
Peace to your Sis and cat...
Thank you. This is my second kitty with diabetes. See my tagline for my first. Diabetes never laid a glove on him. The cancer we never saw coming, however, did.
