My Maine Coon is allergic to almost everything, so we've switched to Hills now. It's well tolerated, no diarrhoea or anything like that. The only thing I noticed after just a few days is that it doesn't seem to be filling or something. He's constantly hungry and asking for more. Or maybe it just tastes so good, I don't know. But the cat is already no lightweight, so I'm worried he might gain even more weight. Otherwise, nothing bad to say about it.

My elderly cat had issues with food. We feed her wet food in the evening and dry the rest of the time. She would vomit after eating everything. We tried changing her food, cutting down on it but nothing worked until someone recommended Hill's Prescription Food. We still feed her one sachet of wet food a day but the rest of the time she has this or the Dental version (which oddly she seems to prefer). No problems since. Worth the money in my view.

My cat has been on z/d for the last 8years due to food allergies pretty much to every protein possible but suddenly he developed runny diarrhoea/every day.Vet 90%sure is IBD..now in a process to find the right diet and cooking.Nothing to be jealous of.

The food is very well received and can help. It's a shame there are no treats.

My tomcat has IBD and tolerated this food really well. However, the taste seems to be a problem for him. It took a long time before he even started eating the food. Now, after three-quarters of a year, he unfortunately doesn’t eat it at all anymore.

Suggested to try this by my vet for potential IBD diagnosis, before going down blood, urine, fecal testing route. It has cleared her up in about a week which is a huge relief. Both cats love the biscuits (nothing was wrong with the other cat but can't feed separately). I'm keeping an eye on the trays as their poop at times is more indicative of constipation but not to a point of concern.

After our tomcat eventually started reacting to his allergy food, we got this recommended by the vet. It's well tolerated, and the open wounds healed quickly. Unfortunately, he gained weight quite quickly (British Shorthair tomcats aren't exactly slim to begin with). At the moment, I'm only giving him half of the recommended amount—the fat content is clearly too high, as is the case with most dry foods.

Unfortunately, this food is the only thing that helps my rescue cat. He had previously scratched his neck bloody, and no elimination diet worked. At the veterinary clinic, they recommended Hill's z/d. Hill's is the only brand that offers hydrolysed protein as wet food (z/d). It really helps him, but despite weighing and rationing the portions, my cat has gained a lot of weight because of this food. It's a shame that there isn't a light version of it.

It took a while but my Burmese has almost stopped overgrooming. However, I am wondering if this food is causing her constipation?

I had bought this food for my old cat lady and she very happily devoured it. Unfortunately she has such a strong food allergy that she even had symptoms with the Low Allergen ones that we had to switch to the Ultra Allergen Free food from Hills. However our experience with other cats tells us that it's a super food for cats with sensitive stomachs or allergies.

I had bought this food for my elderly cat lady, and she ate it very willingly. Unfortunately, she has such a severe food allergy that she even reacted to the "Low Allergen" variety, so we had to switch back completely to the "Ultra Allergen Free" canned food from Hill's. Still, based on my experience with other cats, it's a great food for cats with sensitive stomachs or food allergies.
