Rated 3 out of 5 by Judy24 Helps, but cat doesn't like it much
I bought this product for my cat, who has long-standing IBD. I don't like prescription diets, but since nothing else was helping him, I decided to try it. The first few cans I got from the vet were okay, other than looking like brown Jello, but at least my cat ate it. So I bought a case of the stuff from Chewy. The new stuff was marked "improved formula," which is arguable. It is slightly less gelatinous, but my cat doesn't like it as much. I think it's going to be hard to keep his weight up on this stuff since his appetite is rather poor anyway, despite being on an appetite stimulant. I do mix some of the dried Z/D in with it, which helps him accept it a little better. Can't really say whether I recommend it or not. Yes, because it does seem to lessen his symptoms of IBD, but no because it isn't very palatable. Some of the other cats don't seem to have a problem with it, so I guess you just have to try it and see how your cat reacts.

Rated 1 out of 5 by John The new z/d formulation is horrible.
My cat has an autoimmune disease and was doing well on the old z/d formulation for over a year. He was switched to the new formulation without warning while being boarded because the old stock was used up. He came home with diarrhea and I noticed that the smell of the new formulation was horrible. Sort of like ammonia. I called Hill's right away and they calmly told me that there had been NO other reports of problems with the new formulation. They said only minor changes were made to the fiber and the antioxidants. They sent me 3 coupons. The new formulation smells and looks so different that my poor kitty doesn't want to eat it. We are now trying desperately to find another product that he can eat. Recently, I found out that the new z/d formulation is back ordered and I'm hoping they are changing it back to the old formulation. Please keep contacting Hill's!!!

Rated 5 out of 5 by papillon Cat loved eating the old version of Z/D.
My 14 year old cat has loved eating the older original Z/D formula for years. That formula is what I was ask to review as that is what I purchased from Chewy. Hills now has a new IMPROVED FORMULA and the amount of some of the ingredients has changed. Example-iodized salt has moved up to the 10th ingredient listed in the new formula compared with being about the 20th ingredient in the old formula. Some ingredients, calcium sulfate, cysteine, l-lysine, manganese sulfate and potassium citrate have been added. Sodium Selenite has been removed. Chewy now shows the IMPROVED FORMULA on its web site. That can has red on the label... the old can didn't. To help your cat avoid any possible digestive upset, it is best to gradually add more of the new food to the old food, for about a week, before totally feeding the new food all by itself. I think Hills recommends this also. I'll review the new formula later.

Rated 2 out of 5 by Mikki427 NO to the "Improved" formula
My cat has been dealing with suspected food allergies since February, after many months of agony and stress and many expensive vet visits we put her on the Z/D. She was doing quite well on it, it was controlling her scratching and licking and she was just in general more herself....until the new formula came out, I noticed almost immediately the itching and licking return. I called Hills to see what they changed and they said that they did not change any ingredients but added more fiber and anti oxidants....I am not happy. They also asked if I transitioned her to the new formula, how am I supposed to do that when just one day you show up to the pet store and there is a new formula with no warning that the old was going away?!!! Going to try a LID that has better ingredients to begin with :(

Rated 4 out of 5 by jake9 Necesssary for special diet and cats will eat it - although not their favorite.
Vet recommended for stomach problems. Cats will eat a little of it, but not their favorite. Too bad, because its all hey can have other than their special dry food.

Rated 3 out of 5 by butters It's not me, it's the cats.
As with any Science diet we have ever used, my cats don't like it. Sure the first plateful was gobbled up, because it was new. But by the third can they turn their noses up to it. The dry gets eaten like any dry food, limited, because I (and they) prefer wet cat food and it is better for them also.
My other pet peeve is that you usually have one "flavor". Maybe the reason my cats eat a lot of canned food is because they put out lots of flavors to choose from.
Whoever says cats don't really need variety, don't know my cats.
The texture of the z/d is like gelatin. At least the cat tried it, some of them wouldn't. Besides the z/d, we had used two other prescription diets. I know my cats need a special diet for what ails them but they deserve variety in something that is an important part of their life. So if you could work on the variety portion of it, they may cooperate.
I am willing to pay for the food they should be having, but they deserve variety. If they wont eat it, they wont eat it.

Rated 1 out of 5 by MA2009 New formula is horrible
Prior to the "new improved formula", our cat was doing much better with his breathing and digestive issues. In fact, we had been able to reduce his prednisolone dosage from .8 ml daily to .4 ml daily - and we were ecstatic.
Once the formula changed, our cat threw EVERYTHING up when he ate it - and his breathing started sounding worse. He eventually refused to eat it.
We've had to up his dose again, and are currently working with our vet to find a different food.
Very disappointed that Hill's changed the formula.
