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% |

He purrs while eating it!
By Zoltan on Aug 23, 2020
I brought Zoltan to our house after my mother died. She had been giving him the d/d canned food, and he was a reluctant eater. (Perhaps it was in sympathy with her while she was dying.) His weight had gone down to just 10 pounds. Once we got him to our home, we switched him to the d/d kibble, and he loves it. Not only does he purr while eating, his weight has gone up 3 pounds, and we're going to have to start limiting him!

Very expensive
By CheeseCat on Aug 28, 2020
Was surprised to see the price on this sensitive food. I could buy six or seven bags of other brands of sensitive food for the price of just one Hill's bag. I split the bowl with half of Hill's and half of another brand of sensitive food and my cat threw it up the first week, so I'm sprinkling it in now hoping for better tollerance.

Big help with allergies
By Lovesit on Jun 28, 2020
My out door cat now inside gets allergies so bad that every 4 months he was getting steroid injection to help with allergies. I can not afford to get him tested to see what he is allergic too. I came across this food and got a small bag to see if 1 make sure it helps and 2 he likes it. It does work and he does like it. So happy that it's working and he doesn't dig at himself any more.

Saved our IBD cat’s life!
By Zster on Jun 28, 2020
Our cat was diagnosed with lymphocytic-plasmacytic IBD at the age of 4 years. He went into remission on Hills D/D Duck and Pea formula, not even requiring steroid for most of of that time. This cat is now 16 years old and still doing well on his D/D. His geriatric screens are stellar! Zero kidney, liver, or thyroid issues. We swear by this stuff!

By Gwen on Feb 27, 2020
Timmy was put on dry DD because of diarrhea and vomiting, possible IBS. He likes the food and hasn't vomited as much but still has diarrhea. Not sure how well it's working since it's only been 2 weeks.
