Concerned about 16 year old diabetic cat that keeps loosing weight. I've just got him successfully eating only wet food,, Friskies Pate. but he is always hungry. the vet said feed 2 time a day with insulin. can he have a snack of chicken or turkey in between feedings? or goatsmilk?? also trying to find link to free home testing kits. I haven't started home testing yet.
