I am fostering a 7.29 lb cat with diabetes. Hes only a year old. When I picked him up, they told me to feed him half a can a day, 1/4 can 2x, the Purina Pro Plan Veterinary Diets DM. So half is only 81 calories, and he is NOT overweight. To me he is actually a tad underweight. I can feel his spin when i pet him. I would rate him as 4.5 with 5 being perfect and 10 being overweight. I ignored what they said and feed him 1 can a day so thats 163 calories. I still feel he can eat a little more, maybe up his calorie intake to 180 calories. He has an appt on Tuesday at the shelter clinic, I'm gonna ask if this is ok. I just want to get your guys opinions. Should he be eating more? I feel like I'm nott feeding him enough
