My son's cat, Simon, was just diagnosed with diabetes. He has to give him 2cc's of insulin daily. The vet also said he has to have special food for diabetic cats, only available, (naturally!) through him. If anyone has experience with this, I could use some information. Simon likes canned food. Is an all meat and no grain diet what he needs? I read on line somewhere that fancy feast is low in carbs and good for diabetic cats. I also checked petfooddirect.com and they have meat only cat food. Is there a good quality food that can be bought in local stores such as Petsmart or Walmart? Thanks!
