55 Amazing!!!
Verified Purchase

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

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.

55 Fantastic - solves cat constipation

Best product if your cat gets constipated or has mega colon.
My cat Smarties loves the biscuits and doesn't get constipated (he's got mega colon) He's been eating them for about 3 years now. Have caught his brother nibbling on them from time to time too. If your cat is not keen on biscuits then you can make them into a powder by crushing in a coffee grinder. You must have fresh water available. My cat drinks lots of water each day out of his pint glass :0)

55 My cat's long haul life saver
Verified Purchase

By on 15 December 2013

In 2009 Suki was hit by a car. He disappeared for three days during the height of the summer then crawled through the cat-flap very dehydrated and sporting a broken pelvis. Distraught, I spent my savings and more on a touch and go operation followed by three months in a cage while his pelvis healed. Ultimately his tail died and had to be removed. There began a trial and error nightmare as his ability to go to the toilet without his tail-gate diminished. I had reached the stage, after several enemas and a variety of diets, where I knew his options were ending and for his own comfort and quality of life it would be kindest to let him go. My problem with this decision was that he is such a happy cat, funny, naughty, clever and the best type of pet. new vet recommended Fibre Response coupled with Peridale capsules. This combination has been a life-saver. I give him small meals with a mixture of FR, wet food and a Peridale capsule sprinkled on top. Touch-wood, he has never been better. I may be a bit daft about my cat but I am so pleased I persevered. If your cat has constipation or other problems controlling their toilet, Fibre Response might well be the key. Talk to your vet. It might be the best decision you could make for your cat. I will just say that in all the months he has been eating FR, he has never turned his nose up at it through boredom. What ever it tastes of, it must be quite tempting.
