\n This recently modified formula is awful compared to the previous formula. It turns gray within an hour of opening, even with a tight lid and immediate refrigeration. The previous formula would easily keep for 3-4 days using the same lid and refrigeration. My cat loved the previous formula, always finished the can. He won't touch this new formula as soon as it turns gray, so I had to throw away 80% of each can. I returned the balance of the case to where I bought it, I'll never buy this item again. Shame on Hill's for ruining a previously great food that truly helped stabilize my cat's digestion.\n

\n Hill's Z/D change in formulation\n
\n \n\n \n
\n Our vet recently prescribed Hill's Z/D for our cat due to skin sensitivities. He was doing great on it. Then on November 03, 2025, I purchased a new case of this food, and he won't touch it. These customers are right, the change in formulation have ruined a good thing.\n

\n New formula is awful\n
\n \n\n \n
\n As I’ve read in several other recent reviews, my cat has been doing great on this food for years. The new formula with active biome has caused her to not want to eat it at all, she will sniff it and run away. Now we’re back to square one finding a food that she can eat that she’ll actually go near. PLEASE consider reverting back to the last formula that seemed to be better tolerated\n

\n Disappointing New Chicken Flavor\n
\n \n\n \n
\n My cat has been on this food for about 3 years. He was basically at the vet at least 5 times a month due to severe ear infections and itching. I tried everything and finally he was doing awesome with a combination of the Z/D canned food and ear meds once a week. Now since this formula change to the chicken flavor, I'm back to square one. He liked the new food, but unfortunately it's made him very itchy again, affected his ears and upset his stomach. I transitioned him slowly, but when we got to 50% original flavor and 50% chicken flavor, he started having lots of problems again. It's very stressful and disappointing that the food was changed. We've been trying to find another brand that will work for him again.\n

\n I ordered a case of hills ZD prescription food for my cat. When I got it, 2/3 of the cans were dented. I called and they sent me another case. They took care of me 👍\n

\n New ZD chicken flavor is awful; my cats allergies are back\n
\n \n\n \n
\n Ive been feeding Z/D to my two DSH altered female cats (ages 5 and 6) for 3 years. It solved their food allergies that manifest primarily as intense itching. \n\nTHIS NEW FORMULA IS CAUSING THEIR ITCHING TO REAPPEAR. THE NEW FORMULA IS AWFUL AND BECAUSE I WASNT WARNED I AM ABOUT A WEEK FROM BEING OUT OF THE OLD FORMULA. I HAVE NO CLUE WHAT I AN GOING TO DO BUT NOW I HAVE TO SEE MY VET TO ADDRESSING THEIR ITCHING AND SWITCH TO A NEW BRAND I GUESS. \n\nI came here hoping for info or options…I find out others are also struggling with the new formula.\n

\n New formula change NOT for the better!\n
\n \n\n \n
\n DO NOT BUY THIS CAT FOOD. The “ new improved” formula is AWFUL. Hills… LOOK AT YOUR RECENT REVIEWS since u changed formula.Almost all of them are negative. I have been feeding z/d for a year. The last few months I have struggled to come up with a way to have my IBS cat eat this. Right now I am buying STELLA AND CHEWYS ( great company/food) novel protein rabbit topper and sprinkle that on top. The texture of the new formula is TERRIBLE. ALSO… STOP MAKING UNREALISTIC, STUPID suggestions for pet parents to “ gradually transition” . TRANSITION WITH WHAT??? There is no old formula left. There is really no other alternative for a hydrolyzed can cat food. Novel proteins might be an option. Idk The obvious solution is for Hills to wise up , acknowledge the issues the new formula is causing and FIX IT.\n

\n Definitely got worse\n
\n \n\n \n
\n I have two young cats that have been on the z/d for two months, and they loved it. We originally had some of the older formula (it’s what the vet still had), but apparently we just got some of the new formula…While one cat loves it, the other won’t even touch it because of the smell. I convinced him to try a few bites, and he tried to bury it. \n\nBy the way, your suggestion for people to gradually introduce it into the diet is a bit ridiculous, considering most people wouldn’t have known about the formula change, and therefore wouldn’t have held cans back to transition. Since you no longer sell the old formula, we can’t buy any to help them transition. So it’s a useless piece of advice. I would give it 2-3 stars because at least one cat likes it, but your unhelpful response to people who are upset their cats can no longer eat one of the few foods available to them brought it down to a 1.\n
