Hill’s Z/D biscuits.
I was recommended to try my Norwegian Forest on this diet she has hyperthyroidism & despite being balanced she has an ongoing problem with loose smelly faeces. She really enjoys the biscuits & is holding her weight, but faeces aren’t consistently good so further investigation is required. Both my cats enjoy this diet so certainly worth a try for cats with sensitivity issues.

Amazing
Runny stool samples for months returned nil results so the vets suggested colitis and recommended trying this for our two cats who were only approaching 1 year old. Poor little things. Immediate results. Perfect poops, and all round happier pusscats for some 5 months now. We are thrilled and will not look back.

Life saving producy
I’m happy and relieved I’ve found this product. My cat has been suffering from chronic IBS, bloody stools and diarrhoea for around 3 years. We’ve tried everything, including multiple tests and scans. 2 weeks on this and the blood has finally stopped and her poo looks normal. She’s also much happier in herself. I’m so grateful
She prefers the zd dry food to the wet

The food does what it's supposed to.
My tomcat, who was also prescribed it, eats it, but the cat doesn’t seem to really like it. So, it doesn’t seem to be a hit with all cats, I’m afraid. My tomcat has been having it for years and tolerates it well.

Very good!
Most food gives my Ragdoll really bad runs. But the vet recommended this and it does not! He’s beeb eating this for around 4 years and i’ve has no issues!

Excellent Results & Highly Recommended!
A locum vet recommended this food several years ago for one of my British Shorthair brothers, who was having ongoing problems with his digestive system. Now the whole cat family eat it every day, with excellent results and no more problems. It is a very popular food with all 4 cats.

Has been happily devoured for years.
Thought my two (Bengal + Forest Cat mix) might fancy a bit of variety – but no, they’re sticking with Hills z/d.

Really good
I’ve had a good experience with this food, as my cat is allergic to many things and had scratched herself raw. This is the only food she tolerates really well and eats without any fuss.

Perfect for our cats tummy.
Our cat had crystals in her urine which were operated o successfully. Unfortunately she had ongoing tummy problems and despite different prescription diets from Royal Canin and Hills, nothing changed.
Then the vet checked the ingredients of the Royal Canin and Hills foods and discovered they both contained crustaceans, so she suggested changing to this food and the improvement was fantastic. She has gone nearly 18 months with no tummy problems. She has now be diagnosed with IBS.

My cat loves it!
Our cat kept having diarrhoea when eating popular cat food found in commerce. Then, the vet suggested to switch food for the 3rd time and to try the z/d type for food sensitivities and it resolved the issue. Our cat has been eating only Hill's Prescription food since for the past couple of years already and he had without problems

Super happy for years
For years, the cat (15 years old) has been eating this dry food along with another wet food. She loves both (she won’t touch other wet food at all). She hardly ever vomits anymore, and her coat couldn’t be silkier. New recipe? Neither I nor the cat have noticed any difference. The packaging says “New look, same nutrition and taste.”

Good for years
By now, my tomcat eats this food (exclusively), maybe occasionally a mouse on the side... Due to a food allergy, he had licked and scratched himself bloody. It's been at least 7 years now, his red fur is in top condition, and the cat is healthy with only this dry food.

Stopped sickness and diarrhoea
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.

Perfect solution for allergies
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.

Very well tolerated for severe bowel disease!
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.

Best food for cats with sensitive stomach
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.

Finally, something that works!
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.
