I adopted a cat off the street. 1 1/2-2 years old. Found out a few weeks later that she's diabetic. Sugar count 429. Went on Glipizide for 2 weeks. Sugar count over 500! Back on Glipizide another 2 weeks. Is there anything else to be done? Don't want to have to give her shots or put her down.
I recommend insulin injections. You have to talk to your vet about it. vetcare
