My two Tonks, Lila and Kusha (12 yr-old siblings) have both been diagnosed with diabetes in the last month. They have been on a raw diet (Bravo ground venison with TC feline powdered supplement) for the last six years. Both are considerably overweight because we did not take away their dry food when we switched to raw. Now of course they are on a diet. Am not quite sure how much I need for weight loss but am currently feeding at 2oz twice a day, a bit of dry food for Kusha since he is 16.5 lbs (Lila is 12lbs). My vet is giving me trouble over the diet. He heard some research recently about how 80% of cats on Purina or Hills diabetes diets went into remission within 8 months. He thinks I should feed one of those but wants me at a minimum to try to mimic the protein/fat/carb ratio of those diets (dry matter protein/fat/carb around 52%/22%16%). I can't get that info from Bravo, but I am confident that the protein is higher and the fat and carbs lower in the venison. I don't know what the supplement adds re fat and carbs if anything. I'm going to start adding fish oil because Lila is scratching a lot. I'm wondering if I should actually add more fat to their diet since the venison is so lean. Any recommendations about changes I should make to their diet?
