Hi there! I've been giving my cat Glargine for a few months now. We're up to 4.5 units and when I test his urine it's not getting any better. My cat is still constantly thirsty. I'm wondering if it has to do with the fact that I'm using same bottle of insulin stored at room temperature since December. It seemed ridiculous to throw away a bottle of insulin when so many people need it, etc. I looked on this board and the consensus seemed to be that as long as it wasn't cloudly it was okay to use. Anyway, any thoughts are greatly appreciated! Thanks for reading! I'm taking him to the vet this week.
