I thought my cats would love to have another type of hard food other than science diet due to my male cats urinary issues. They had been on science diet for quite a few years after being on the prescription science diet for urinary issues cat food. We luckily graduated to nonprescription science diet because we wanted him to stay on a brand that helped with urinary issues. There are very few brands that are made specially for cats with urinary issues. I was so excited to see that Purina now had a hard cat food for cats with urinary issues and it was a seafood flavor. I was so excited for my cats. The excitement died almost immediately when I noticed my cats were eating the bites of the science diet as I had started it by mixing the two. They were not eating hardly any of the purina. Over time, I noticed my cats were begging for treats a lot more and the Purina food in their bowls wasn’t touched. I decided I had given Purina a long enough chance and my cats felt the same way. I went to Chewy,, set up auto ship for my cats original science hard cat food and received it within just a few days. My cats love their hard food again and Chewy saved the day. Thanks Chewy and Science Diet.

So I’ve been ordering the same product for a year or so and this time it was the same bag, completely different product. My cat will not eat it and there was no explanation or “new formula” warning. I don’t blame chewy per se, but when a product changes, distributors and consumers need to be made aware. Having a huge expensive bag of food my cat won’t eat potentially could have been avoided.

The formula/recipe change was not disclosed. I noticed the different look of the kibble, nothing different on the bag, called Chewy and no notifications on their end. I thought it was a slip up at the factory, got a replacement. unfortunately, it was the same item. My cats vomited and could not eat it. I have trashed an unused bag. After being unable to transition to a new food (since they won't eat it at all) and have selected a totally different brand. 0 stars is not an option....

He loves it!

Charlie has not had issues since he has been on this food. The last time he had a UTI was several years ago before he got on the low ash diet. He has been on Hill’s Science Diet ever since we realized how dangerous it was for him to be on regular food. So for the last several years he has been enjoying good health on HSD brand.

Formula Changed Without Notice

As many, many other reviews here have noted, Hill's changed the formula completely between one bag and the next. I have been getting this food for over a year now

As many, many other reviews here have noted, Hill's changed the formula completely between one bag and the next. I have been getting this food for over a year now with no issues, and it has kept my male cat with a history of urinary issues healthy, so I planned to keep feeding it to both cats for.... well, for as long as Hill's sold it. But this new formula means they might as well have discontinued it entirely. I honestly find it dishonest and shady that the brand did not advertise this change ANYWHERE--not even a picture of the very different looking kibble, or a little blurb on the packaging that says "new formula." I noticed it was different in size and shape as soon as I got it, but hoped it would be relatively the same formula, even though it smelled different, too (worse). My cats will eat it, but both of them swallow excessively and pick their lips afterward, and my male cat makes pre-vomiting noises and motions before visibly swallowing back the vomit after every meal. I don't feel safe feeding this to my cats for much longer, I don't have any confidence that the new formula will be effective, and I no longer trust the Hill's brand at all. I will be looking elsewhere for future urinary diet food.

Formula Change without Notice

Extremely disappointed in Hill's, I will never buy from them again. My boys have been on this food for years and they loved it. It resolved my older one's urinating

Extremely disappointed in Hill's, I will never buy from them again. My boys have been on this food for years and they loved it. It resolved my older one's urinating issues. I noticed the change immediately (the smell is awful) and my boys pick around it and are having tummy issues now. Hill's has lost my respect and their credibility. For those wondering for a new formula, I ordered Purina Pro Plan Urinary. Fingers crossed. Shame on you Hills.

I have been buying this food for years with no issues. This last order the kibble was darker and tighter in shape and Strong smell. Both my cats ate it at first then puked it up immediately. Tried 3 more feeding times and my female cat won't even touch it now and the male eats it then pukes it up....Hills ruined this cat food for me and my cats. Now I have to start the journey over again with another brand.

My cat would hardly eat this. I called chatted with Chewy online and was told that Hills has changed the formular of the food. I was offered a refund by sending the bag back. I am 73 years old and it would be a hardship me me to lug the bag and send it back...I had to purchase from a pet store a different brand in a smaller bag

Before the manufacturer changed the ingredients without telling the consumer or Chewy! this was always a staple in our home. All 4 of my cats are males and I appreciated the Urinary tract recipe that my vet told us helped with crystals that can show up in their urinary system. The last bag I ordered was definitely not the same as the others, which I noticed immediately. Within 24 hours, all 4 of my cats had severe diarrhea and vomiting. After looking it up on the internet, I found there are NUMEROUS cat owners with the same problem. I thank CHEWY for refunding my $, but I do NOT appreciate Hills changing the ingredients behind my back just so they can make more $. I can't find the older formula anywhere.

I have officially canceled my auto shipment and have to find a replacement for my cats ever since they they’ve changed the new formula. All of my cats have been vomiting and not able to eat it. Thank goodness for chewy’s exceptional customer service as I got a refund and I will be looking elsewhere.
