  • finicky cat loves it but the 5 stars go to Chewy

    By on

    Hills abandoned my finicky cats previous favorite food, took 6 different foods to find this that he like even better than the abandoned one. chewy is actually the star here though. They sent an email explaining why the auto ship would not happen, then called and asked how the cat was doing then sent a post card from a Florida vacation to my cat. All this to retain a small account. Great business model! Hope the excellent customer service continues now that they have been sold to a mega pet food company.

  • My kitty loves Science Diet Age Defying Cat Food!

    By on

    I was so happy to find that Chewy had this great price on my cat's favorite dry food. It is so convenient and cost-effective to get a big bad to last for months with free delivery, since I ordered so much. He loves it!

    My senior cat is 16 and vomits up his food frequently. He doesn't gobble mass quantities, he picks delicately. He has less digestive trouble with this and seems to like the flavor. Unfortunately it is full of grains and fillers. So we are back on the hunt for something he can stomach that meets my guidelines for nutrition.

  • Nice and easy

    By on

    I use science diet cat food for my cats since we first got them. My cats are very healthy, and dont have any health issuse with them. Due to the fact that the quality food we give them. Using chewy has been a great time saver. You can not get our cat food at the big stores. You have to Buy from a pet store,which I think are a bit over priced. Chewy was a little cheaper, and it came right to the door. That is what I like most about chewy. It comes right to your door. You can set up repeat deliveris, so you neever have make a trip to a pet store. Also never run out of food for you pet.

  • Better for old mouths

    By on

    This Science Diet is in MUCH smaller kibbles than the Optimal Care variety. It's easier for my supersenior cats to chew. My younger cats like it too.

  • Kitty Doesn't Like It

    By on

    My cat, Kitty, loves the Science Diet Optimal Care but only eats the Hill's Science Diet Adult 11+ Age Defying Dry Cat Food reluctantly. At least she likes it better than the grain-free and by-product free dry cat foods.

  • Healthy diet for your pet!

    By on

    My cats live long lives (16 years, past two cats) on this diet w/ minimal visits to the vet. My current feline is 12 years old and going strong. In 12 years, she has only been to the vet once. Highly recommend!
