That blood glucose is high for a cat! If it is attributed to diabetes mellitus, it can also cause a cat to urinate a lot which will, in turn, cause Junior to drink a lot of water. However, there are other things that can also cause a high glucose. To determine if it is secondary to diabetes, the veterinarian also needs to run additional blood work and check Junior's urine. Continue to work with your veterinarian to determine what is wrong with Junior. Thank you for using pet coach!
