I forgot to mention, I have been feeding every 2-3 hours (total of 3 cans daily) in an effort to keep BG steady. I purchased the PetSafe 5 and use it when I am at work and through the night. Is this the right thing to do. I am trying to have him lose about 2 lbs. I have read to not aim for more than 2 ounces per week. He is currently 15.8 pounds and I think he would be better off at 13. He's s big male. I can feel his ribs and as per Dr. Lisa's advise am paying attention to the area from his head to shoulders. He seems pretty well muscled????????????? This is so consuming!!!!!
