Hill's Z/D change in formulation

philinindy

1 month ago
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.

Thank you for your review. We are disappointed to hear of your experience. We did update the formulation of the Hill's Prescription Diet z/d products to add the ActivBiome+ Multi-Benefit Bundle. This is an advanced blend of prebiotic fibers and antioxidants to support digestion, bolster the immune system, and support organ health. To maintain our leadership in nutritional health care for companion animals, we periodically make changes to product formulas to incorporate additional health or product design benefits. Despite the favorable benefits gained through the reformulation, our pets are creatures of habit and may need a little help to get accustomed to the change in the food. When the formula is changed, we recommend a transition from the old to the new formula over a seven day period.

My Cat Did Not Like It

Disappointed Catmom

1 month ago
My cat started a food trial to see if he has a food allergy. He is supposed to only have hydrolyzed food. He really likes the Royal Canin hydrolyzed kibble, but they did not have a wet food, which I wanted to have on hand to mix with his prednisolone steroid to get his dose in him. He prefers wet food over kibble, but it's no longer part of his diet while on his food trial, unless it was hydrolyzed. Hill has the only hydrolyzed protein wet food. I saw the reviews that they had changed their formula and people's cats no longer liked it, but I thought it worth a try. The texture was a very thick mousse. He ate a little bit, but after the first introduction to it, he didn't want it again. I will be returning the remaining cans.

No, I do not recommend this product.

New formula is awful

Kelly

1 month ago
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

Disappointing New Chicken Flavor

Britt F.

1 month ago
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.

New ZD chicken flavor is awful; my cats allergies are back

Anna S M

2 months ago
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. THIS 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. I came here hoping for info or options…I find out others are also struggling with the new formula.

New formula change NOT for the better!

Tb2025

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.

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. By 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.

Cat won't touch it. The consistency is like peanut butter, not a pate. Not appealing at all - doesn't look anything like what is pictured on different sites.

Thank you for your feedback. We are disappointed to hear of your experience. While it is difficult to tell the exact cause for this change in texture, we can assure you that this variation has no impact on the nutritional value of the food. Some possible causes of the variation are the freshness of the product or temperatures the food has been exposed to during distribution. Additionally, a freshly produced product can appear softer or stickier and will generally increase in firmness as it ages. If maintained in a hot environment, it stays moist and soft for much longer than if placed in a fridge and exposed to cooler temperatures. Hill's Pet Nutrition.

      Why does cat food need Vet authorization?

      1. 3 years ago
        A couple different reasons: some prescription foods are not "nutritionally complete" and can results in deficiencies if used exclusively for a long periods of time. Also, they are not a stand alone solution to health problems, and the animals should be under the care of a veterinarian.
