Hill's Prescription Diet Feline m/d Diabetes Care - Chicken - cat dry food

Despite my efforts, it's impossible to get my cats to eat these kibbles. I bought one bag for diabetic cats and another for sterilised cats from Hill's, but even with five cats, none of them want it. Given the price of the bags, I hate to throw them away. It would be a good idea to offer smaller packs to try out first.
