Review: Well tolerated - Works within 6 hours for my cats. Highly recommend for consipation
Review: Worth it - I have a ragdoll cat who developed Clostridium Perfringens (caused by house move stress) which resulted in poo on the floor most days over the space of a year - mostly puddles. My only saving grace was she was only doing it in particular areas, so I could put rugs down and clean from that. Tried everything - Vets trips, antibiotics, powdered probiotics, changes of food, Feliway, you name it - powered up by the fact she has feline Coronavirus (which I didn’t know). The Vet Specialist suggested this kibble. Game changer. Noticed a difference straight away with the consistency improving - but after a month - I’m afraid to type it - the poo outside her litter tray has stopped. And her poo actually looks like poo. So even though in the description it says for constipation issues, this Fibre Response has solved this problem of chronic diarrhoea. This product might be more expensive, but it has made our whole household happier, mostly Kitty who has gained weight to normal, and no longer runs to her litter trays 40 times a day with ring sting. It works and I thoroughly recommend this kibble.

## Questions & Answers

**Q: Is fibre response shipped to Canada and if so, what is it worth in Cdn. dollars**
A: no soory , we don't ship for Canada. best regards

**Q: What is the fat content?**
A: Hi. Fat content in a 4kg bag is 22.0%. Kind regards Mr Pets

**Q: Can this be fed permanently as main diet for cats?**
A: Hi. Yes it can. I am assuming that your cat has a digestive complaint as this is a veterinary diet and is supposed to be used on the advice of a vet. That said I have fed both my birmans almost exclusively on this food for nearly 2 years and only one of them has stomach problems. They seem to enjoy it a lot. They don't like the wet version, but I give them a pouch of sensitivity control wet food most days for a bit of variety. Make sure you give the right amount of the dry food,  as its high in calories. Hope that helps.

**Q: Can my cat have other his normal pouches aswel as this food?**
A: Yes, my cat has half wet food (his favourite) and half fibre response.

### ⭐⭐⭐⭐⭐ Bought for the second time – highly recommended!
*by A***A on 28 June 2026*

I’ve now purchased this food for the second time, and I can honestly say it has made a real difference for my cat. My cat has digestive issues and occasional constipation, and after switching to Royal Canin Fibre Response I noticed a clear improvement. Digestion became much more regular, and my cat seems much more comfortable. The kibble size is good, the food is well accepted, and my cat enjoys eating it every day. Although it is more expensive than regular cat food, the results make it worth the price. I’m very happy with this purchase and will definitely continue buying it. Highly recommended for cats that need extra digestive support, especially if recommended by your vet.
