  • Works Wonders!

    By on

    The vet wanted to us to use Hills Metabolic but I suggested this instead. He agreed that we could try this. Our female cat has lost 4 pounds in 4 months and is continuing to lose. She has increased energy and her coat is looking amazing. I would say that is a victory. She loves the food and meows as soon as we open up the pantry door to feed her. It is a nice size and a great bargain through Chewy! They shipped it very fast after receiving the prescription from our vet.

  • Amazingly quick delivery!

    By on

    So happy with the speed in which my cat food was delivered. I normally buy my diabetic cat’s food with a prescription at Petsmart. Whatever the reason every store was on back order and I was running out quickly. After placing my order on Chewy.com they contacted my vet and had the food on my door step less than 48 hours later! Will definitely be purchasing from here now on! Thank you!

  • Great nutrition for round kitties =^.^=

    By on

    My two kitties were a little "rotund" when I adopted them. (They don't like being called fat. Lol) We tried all kinds of specialty foods and then our vet recommended Purina OM. Although my cats are not picky, they really like the taste. They are able to get in enough to get the daily nutrients they need and stay healthy while finally attaining a more desired weight. The vet is happy and my cats are happy. Chewy.com sells it a little cheaper than the vet so we just started ordering it from them because we love their service. It literally came the next day.

  • Great Option for pudgy kitties!

    By on

    My chubby fur-baby just started on this diet, so it will take time to see improvement, but so far, she seems to really enjoy the taste and seems to be satiated for longer! I look forward to seeing results for her!
