Our cat Indy has been managed quite well with Vetsulin for three years. I came to this site today because we're freaking out due to Friday's announcement that Vetsulin is being discontinued completely now. We're nervous about "transitioning." Do we have to give him part of one product and part of another for a certain period? Do the "lucky few" who have good luck with Vetsulin always do as well or better on the other products?
