Bought this for my cat as she has a tummy issue recommended by our vet She loves it can’t get enough of it She is now putting on weight & tummy issues are going slowly only had one bag at the moment but we are happy with it

No issues for years, and now I'm cleaning up vomit everyday!

They have changed the formula not just the packet. My cat used to tolerate the old version but he can’t eat the new version because he gets constant diarrhoea from it, I don’t know what they have changed but the new formula triggers sensitivities.

My cat has been on zd biscuits for 3 years as he has had chronic pancreatitis and triaditis he's incredibly sensitive and needs to keep to what we know, I did my usual order of them and when they turned up I noticed the packaging was different I thought surely they wouldn't change a biscuit for sensitive cats without a HUGE warning Nope apparently they have one very poorly cat and a vet trip thankfully I used good sense to immediately take him off the biscuits! Why do this to sensitive cats!

We spent nearly £700 with various tests at the vets to find out why my cat suddenly had sickness and diarrhoea. As a last resort after trying everything except invasive surgery, the vet suggest a hydrolysed diet. We didn’t think it would work after trying various diet changes over the previous weeks but this cat food stopped the problem within a week. We’ve got our old cat back now and so glad we were able to find the cause.

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.

Switched to Vet-Concept, tastes better and suits our tomcats much more.

Finally, I had found a dry food that both my cats could tolerate. No more diarrhoea. Two days ago, I started the new package, and now they have diarrhoea like water. I’m very disappointed. Never again.

Both of mine love eating this dry food the most and tolerate it really well.

This is quite disappointing. My cat has been on ZD for 10 years without any issues. Switched over and been flaring up since. Not I have to look for another food and manage her poor itchy skin again :(

Cat with food allergies ( derm & gastro) on old formulation for years - absolutely no problems. Recently started new formula - he’s basically now a papular itch with whiskers! Even the cat without ever having allergies has developed severe itching around neck & ears! Hills - what did you do? Both will be switched to RC this week.

Used old z/d formula with no issue, now new formula after a week or two cats are vomiting daily due to it. (Indoor cats no other changes to environment or diet) Avoid activbiome+ formula

Thanks to the new formula, my cat now only eats the dry food reluctantly, spreading her daily portion over two days… She doesn’t want the wet food with the new formula at all anymore. Brilliant – it was the only complete food she could tolerate due to her allergies until now… Now I’ll have to spend months searching all over again…

One of my cats has been on ZD dry food for about 3 years. She loves them. She also takes tablets from the vets to suppress the urge to scratch. She is able to eat most regular wet foods as long as she has these biscuits. My other cat thinks they are treats when she finds a stray one lying around. She transitioned easily onto the new formula without any problems.

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.

The old formulation was the only hydrolysed diet I could find which had absolutely no fish in it, as this seems to be what makes my cat ill. Unfortunately the new “improved” formula now contains fish oil. Despite following the advice to transition slowly I once again have an ill cat and am back searching for something she can eat without vomiting. Be very careful of the new version if your cat has any sensitivity to fish.

Our cat Barny had CBD and was seriously ill. In the meantime, he has recovered very well. After consulting our vet, we bought Hills ZD and are very satisfied. He accepted it right away, tolerates it very well, eats it with great appetite, and his coat looks fantastic. High-quality food, definitely recommended! We also tried the wet food in the summer, and it was licked up with relish.

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.

Our cat use to vomit and diarrhea blood as she has very sensitive stomach. Ever since we put her on a strict diet of z/d dried food, she has been great. I wood recommended to all cat owners that have similar issues. The price discounts at ZOOPLUS are a great help.

I had been feeding my cat a different food for ages, but despite it being hypoallergenic, my cat was scratching herself a lot. Only cortisone helped. Now I've been feeding her the new food for 2 months, and she hardly scratches at all anymore. Her coat has become very soft and shiny. If it works, the price is worth it to me, and I will definitely keep feeding her this food.
