Wondering if Dr. Marty Nature’s Feast is worth the price? Rainey is a short-hair domestic, 5 years old and always seems hungry. He me-ows demandingly many times a day and then leads me to his auto feeder. The auto feeder (PetNet) gives him 3 meals a day When he weighted 13.5 lbs. the Vet told me to switch to Purina ProPlan Weight Management dry cat food. He gets the chicken and rice formula. I did that. Now he looks leaner, yet he still weighs 13 lbs. I watch Dr. Goldstein's video and he says cats should not eat corn and corn gluten in the third ingredient on the list of the Purina. Purina cost less that $15/month and Dr. Marty Nature’s Feast would cost over $400/month. Still I love my kitty. Any advice is appreciated.
