    I've been experimenting with different dry food for my 7 cats.We have 2 1 yr. old kittens + 5 adults that were rescues. Two of them are brothers. They aren't too finicky but I've discovered that this variety appears to be their favorite. The large size is a little off-putting; but that is the only down side to this food. The price is the best & it arrives within 2 days. Way to go CHEWY!

  • Science Diet cat food is wonderful

    By on

    Since switching to Science Diet cat food my big boy Jax eats half of what he used to eat with the other store brands. It fills him up and there is no begging and meowing for more food throughout the day. I have also noticed a dramatic change in how "less smelly" his bowel movements are since switching! This is wonderful & btw this momma is very Happy! We will never purchase another brand again! We are sold on Hills.

    My Sophie is 7 years old and been on Science Diet all her life. Somehow I never came across this variety of food. She is a finicky eater but absolutely loves this food. It will be my go-to food for her from now on.

  • Cat loves it

    By on

    I'm giving only 4 stars because I don't think my cat has been on it long enough to see how her body does. But so far she's loving it. She got bored with her old food so I decided to give this a try. It was recommended to me by a friend. Right now I'm still mixing old food with new but my cat is excited about eating again.

  • Good food for my cats

    By on

    I have several indoor cats and have had trouble finding a good food that they ALL will eat. One of my cats even has issues with ingredients in a lot of other foods. This one seems to do the trick. They all eat it and no one has barfed it back up afterwards. The switch over from their other food went very well also.

    When I first adopted my two kittens I was feeding them Hill's Ideal Balance for kittens, they are picky eaters and they loved this brand. When it came to switching their food to adult, I struggled to find something they would like. I first tried the same version of Ideal Balance but for adults, but they didnt seem too excited. When the shipment for Science Diet arrived, my cats ripped the bag to eat what was inside! They absolutely love the flavor!
