Blood in the urine would not be caused by his insulin, so don't worry :) It's likely that he has a UTI, as these are extremely common in diabetic cats. If he's acting normal otherwise, I wouldn't consider this an emergency - but I would definitely recommend calling Meatball's regular vet in the morning or taking him in for an exam. You should continue on his regular insulin dosing schedule as directed by your veterinarian unless he/she instructs you differently.

    Diabetic cats are more susceptible to urinary tract infections. Good observation! I definitely recommend that you take Meatball to his regular vet to test his urine to find the source of the blood and treat appropriately.
