Yesterday our 13 year old cat was diagnosed with diabetes. Our vet sent us home with 2 cans of Purina DM and a bag of the same in the dry version. Now we read on your site that the dry Purina DM is not recommended nor is any dry food. If you must feed dry food, absolutely do NOT feed Purina DM because it is poor quality for a diabetic and also quite expensive. Is that still true and shouldn't our vet know that? Thanks for any advice!
