My cat is about 5 and I wanted to introduce other brands to her diet (she spent the last few years eating the purina one chicken flavor). She is super picky but it seems I got it right this time. I always add a little bit of water to her dry food for more hydration (which she doesn’t particularly like), but with this one she was still all over it. Also I noticed after a week or so that her fur felt a little softer. Can be a coincide but I thought it was interesting. I may give the wet food a shot as well, even though it’s always a struggle to make her eat her wet food.

Perfect stools and digestion!

My cat Lucy has had some sensitive tummy issues and a lot of mushy poops. Vet suspected it was her diet. We tried different foods to see which would improve her

My cat Lucy has had some sensitive tummy issues and a lot of mushy poops. Vet suspected it was her diet. We tried different foods to see which would improve her poops, but didn't have much success. When I looked at the bag of this food, it said right on the back that it would help stool consistency, and that was what I needed! I finally switched her to this, both the wet and the dry versions, and her poops have been so much better! She's now pooping logs instead of blobs. Both of my girls like the dry food!

This Stuff works!

My poor kitty has had digestion issues for a long time. I tried every suggestion, all kinds of wet, dry, meat, fish, poultry combinations and brands.... and then

My poor kitty has had digestion issues for a long time. I tried every suggestion, all kinds of wet, dry, meat, fish, poultry combinations and brands.... and then the vet told me to try this. It works! You have to give it time, but after three weeks his digestion is returning to normal. And the best part is he likes it, and so does his brother! I am so relieved. Thank you, Hill's Science.

No Go! This was not a good choice!

I am not at all happy with this choice as my cats will not touch it. I feel so bad because they did not eat at all throughout the night. They smelled it and walked

I am not at all happy with this choice as my cats will not touch it. I feel so bad because they did not eat at all throughout the night. They smelled it and walked away and my babies are not picky girls. I love HIlls brand, just not this one.

Let down

I was hoping after seeing the reviews that this product would help my cat's diarrhea. Instead it made it worst.

Not Interested

My picky GI cat isn't a fan of this dry food and he vomits it back up after eating. Will be sticking to dry Royal Canin GI!

Excellent cat food

My cat loves this food and it's healthier than many products on the market. The price is a bit high, but it's worth it. Highly recommended!
