My cat TJ was diagnosed a week ago with Feline diabetes. His glucose level was 598. He is a small cat, around 8-9 lbs. He is 8 years old and has never been overweight (he looks to be underweight). I'm trying to determine the best pet food to feed him and have been trying different brands. The problem is that he is not eating a lot and doesn't seem to want to drink water. He has been on insulin (1 unit of glargine) for about a week but I've been giving him .5 units for much of this time as he hasn't been eating a lot. Should I not give him the insulin at all if he doesn't eat much? I'm taking him for a glucose curve test tomorrow. Any recommendations on pet food he'll eat? I've tried Instinct, CORE and others. Thanks for your help.
