Pets can be sensitive to sudden changes in their diets. For this reason, it is extremely important to follow a gradual transition plan to best support your pet's health and product effectiveness. It is recommended to follow at least a 7-day transition plan before exclusively feeding your pet a new food. Cats will often refuse mixed diets, so we recommend adding the new food to a separate bowl from the old food. Start by mixing 75% of your pet's current diet with 25% of the new diet on Day 1 and Day 2. On Day 3 and Day 4, mix 50% of the current diet with 50% of the new diet. On Day 5 and Day 6, mix 25% of the current diet with 75% of the new diet. On Day 7, you can feed your pet the new food exclusively. Ask your Veterinarian about the best way to transition your pet to a new food.
Transition Day | Current Diet | New Diet |
---|---|---|
Days 1-2 | 75% | 25% |
Days 3-4 | 50% | 50% |
Days 5-6 | 25% | 75% |
Day 7 | 0% | 100% |

really works!
By TippII on Mar 1, 2021
1 of my cats is very overweight, he is a very large cat by nature, but eats like a garbage disposal. He has lost quite a bit of weight on this food, you can see his waist line again. Being over weight is not good for them, may look cute, but he was not as active as he should be and he is 10 years old. This food has made it possible for him to run up and down a flight of stairs now, where as before he was a careful walker. Has a long way to go but this food is worth every dime.

My Wolfie Loves it!
By Wolfie on Dec 11, 2020
My pleasantly plumb cat Wolfie loves this! The chicken flavor is his fav. The fiber in the small pellets size has him going to the bathroom a little bit more often than usual but that's the whole idea! For him to expel any excess food rather than store it and put on the weight in his belly area. He has a sensitive stomach as well this doe not irritate it. I can't "weight" to see his result is a couple of weeks.!

Pleasantly surprised
By Meg22 on Jan 19, 2021
I was afraid that my chunky cat would not like this food because it is "diet" food, but she loves it! She sits by her feeder waiting for food to drop. :)

Huge difference
By Amtkk on Jan 14, 2021
I am very pleased with the quality of this food. Although, I believe, it is quite expensive, it has made a major difference in my cat’s digestive health. No more diarrhea.

Pet lost 2 lbs
By Patty on Aug 10, 2020
Cat was always hungry and overweight before his 2ñd bday! He would cry and I would feed him. However when I started feeding him less and ignored his cries I realized he was not starving and he just liked to eat. He lost the weight the doc told him to lose(2 lbs) and he is a happy cat. Even with less food.

Fat kitty cat
By Becca on Aug 26, 2020
I have a very fat cat and have been getting Hill’s from my vets. But sometimes they run out and it’s hard for me to find. Ordering from Chewy’s was easy and now I can order and receive timely. Thanks.
