Verified Purchase

Great product, was recommended by a vet friend of mine and has worked a treat. Would definitely recommend. My cat Wilson was struggling with passing stools and within a couple of days of starting this food he is regular again. He really enjoys the food and actively seeks me out of the bowl is running low.

We brought this on recommendation from our vet as our cat was diagnose with idiopathic mega colon. The vet was not positive about about his future. He’s been on this 3 weeks now and Its made a huge difference to him. It’s a condition we have to manage and this is essential now to his well being

55 Amazing!!!
Verified Purchase

By on 14 February 2019

I was getting really concerned for my cat as she was struggling to go and only managing little hard bullets! She was obviously distressed and crying before needing the potty. After reading the reviews I thought I would give these a go, even though they are pricey they are going to be 100's less than the vet!! Anyway, by day 2 my beautiful baby had done a huge one!! I have never been so excited about poo in my life! Haha! I've seen her drink lots, which is rare, so that's another bonus! Her eyes are brighter and she seems much more chirpy! I highly recommend these miracle biscuits if you have a cat like mine who won't touch any pastes potions or pills!!

55 Very good
Verified Purchase

By on 4 January 2017

It is a very good food. My cat started having problems with hairballs. None of the other foods helped, not even any to tackle hairballs. I mix this fibre food with other and it helps my cat with digestive problems. Since I started using this food, the hairball issue seems a lot better.

Gastrointestinal vs Gastrointestinal Fibre Response


What is the difference between Royal Canin Gastrointestinal dry food for cats and Royal Canin Gastrointestinal Fiber response ?
My cat weirdly loves the first one but not the second.
She gets that kind of dry food because she is always very constipated.

  • VioVet Staff

Royal Canin GI Fibre Response is more aimed at cats who's stools need softening and only really for use in the short term (3 to 4 weeks). This helps ease constipation. The normal Royal Canin GI food is aimed at general intestinal health, promotoing normal function of the intestinal system.
These are both prescription diets so it is recommended you discuss any changes with your vet.
