    If my cats see the slightest reflection in their food dish they let me know it’s empty. It may be 3/4 full but they will tell me it’s empty because they saw themselves. They just love this food so much. It’s also great that there is such a variety for all customers to choose from and having it sent right to you, cheaper than if I went to my local pet shop.

    My shelter cat came home with me on this food and I had never heard of it so I looked at the ingredients and I was impressed. Very few of the stores around sell this brand, but Chewy is the best price I can find. My cat loves it and she doesn’t overeat because it’s full of nutrition unlike other foods.

    My 3 old & 1 young cat like this food. Have been using it for years. Keeps them healthy. (They are approx.14 & 16 years old). I believe it is important to feed them well to avoid health problems later in life, & to have a lively, healthy cat that is getting good nutrition. Am happy with this product.

  • Our Cat Loves This Food

    By on

    We recently transitioned out Cat from Kitten food to Adult, we first chose the Indoor Cat and he had a hard time eating it because the kibble was large so he did not eat well. On our Vet's recommendation we changed him to the Optimal Care which has much smaller kibble and he loves it and is eating it, no problems.

  • Excellent daily food

    By on

    My five year old rescue seems to be doing very well on this dry food as her main diet, supplemented with about 2 ounces of Hill’s Science Diet canned food for hair ball reduction. No hair balls. Just a happy, healthy, active cat.

  • Only cat food that my cat will eat.

    By on

    My cat is 10 years old. When I got her from the Humane Society, she was very small. She was 4 months old before she reached the weight requirement for adoption. After I brought her home, she had diarrhea. I started her on Science Diet Sensitive Stomach and her diarrhea resolved. I kept her on the Sensitive Stomach formula for a few years, then switched to Optimal Care, which she tolerated well. I tried other brands of cat food; i.e., grain-free, and she wouldn't eat any other brand of cat food but Science Diet. I've tried to give her chicken and tuna in the past as a treat - she wouldn't eat it. I've never had a cat like her; she will only eat Science Diet.
