Hi, I'm Angela and have a 10 year old male who has had urinary stones for years and was recently diagnosed with diabetes. My Simon has been on glipizide pills for 6 months and it's not helping. Vet wants to try the transdermal form because I'm Leary about giving insulin. Had a cat years ago that the first dose caused a diabetic coma and I had to rush him to the vet. Has anyone ever used this? He's on DM wet exclusively and it's not helping either. Thanks so much!
