How to help your cat transition to a new diet?

Changing your cat's diet can make a real difference to their health but remember that any transition has to be smooth and gradual.

Great for nervous cats
My little one is very very anxious and with only a few days on this food is already more settled highly recommend

EXCELLENT
We've moved two of our cats on the this, one suffers from separation anxiety and gets cystitis, the other will wee on things when we go away. Both are now so happy and content ☺ worked sooooo quickly too, and we only give them 10grams each a day added to their other food, two happy kitties 😸

Effective solution for a stress prone cat
We've been using this food for almost 3 years or so. Its been a very effective solution for our senior rescue cat, who we've had for 3.5 years. When we first adopted her, we tried multiple strategies, including plug-in de-stress scents. This food seemed to make the difference. Now, after several changes in where we live, and the recent introduction of a puppy, she's doing very well, with only minor relapses in her over-grooming. We've always mixed the food 50-50 with a "standard" dry .

Incredible stuff
We have been fostering a traumatised adult cat for over 6 months now. She'd made progress but was still attacking strangers that came in the house due to her past experiences. Speaking to our behaviourist we understood this response was fear based, not pure aggression. We tried so many things but as a last resort I found out about this food. 3 weeks later and this cat is completely changed. We've even introduced her to a new person and she was confident and happy to meet them. Amazing

Good
It didn’t help with calming my cat and stopping her having accidents in the kitchen, but she stopped pulling her fur from the tummy, which is also stress related.

Didn't make cats calm
No difference in temperament from food. Better off buying more nutritious food and adding a calming supplement! Waste of money!

Amazing !
This product has completely changed my cat's behaviour. Over the years I have spent thousands on on trying to sort out his nervous behaviour . He was terrified of anyone new in the household, noise, other cats . He has suffered from very upset stomachs . Nothing could be identified as the cause. After just a couple of weeks of using this food he now takes treats from visitors , is undisturbed by loud noises & has no more upset stomachs. Unbelievable - wish I had found it years ago.

It’s Helped!
My very mardy jumpy cat has been on this for a year now recommended to my by my cattery. So far so good she’s a lot calmer now so will carry on feeding her it.

Excellent
Had problems with my cat since a kitten due to stress, she comes from a multi-cat household and began urinating on the carpets or rugs and nothing worked till I started feeding her the calming food! She was so unsocialable before as well and now she comes to us for strokes and cuddles all the time. A few month in another cat I have started showing signs of stress and anger towards the others and I’ve put her on the food too and no problems anymore :)

Honestly changed my cats life and health!
My cat has had heart disease since he was born but wasn't discovered until he was 18 months old. He has been on medication since then and has 6 month check ups. Along with the normal heart disease symptoms he gets very anxious and stressed. This can be the slightest thing, recently pollen allergies causing him to pull fur out he's so itchy have made him anxious and my little sister has been in and out of hospital. He isn't close with her but just the absence sent him into a spiral of not eating, weight loss and mood issues. I came across this in a discount bin because there was a tiny rip in a bag. I thought why not! Cannot hurt to try when the vets can't do too much. I brought it home and when he next decided to come home he made a beeline for the bag and literally started to rip the bag open himself. He's started to eat again, I mix into wet food and he will eat it. He's staying inside a lot more and his mood with me and his siblings has increased ten fold. This is going to be his staple from now on and I couldn't be more grateful!

Life changing
Molly was a happy cat.. She lived with her 2 sisters and 3 dogs and never had a problem. We moved and she loves the new house but after 6 months she started to pee on the rug by the Rayburn. Or even in a pan. We couldn't understand why. We changed the cat Litter and hey presto we thought it was sorted so bought a new rug. Well few weeks into it and that rug was getting soiled. She is 8 years old... It was behaviour not medical.. Since having this food it's changed everyone's life! NO PEE ON A RUG!! In fact she is now usIng other cat trays even if we are in the room!!
I can't tell you how amazing this is... I don't know how long it will last but It really has helped... Worth a try!!

It Works!
I did not think it was making much difference but when I ran out of it, my cat seems much worse.... So it must work!

Some Improvement
Been giving my 13-year old skittish and scared cat this food ONLY for 4 weeks now, along with 2x Pet Remedy plugs in the flat. She has shown a slight improvement -- she now sometimes plays with one of the other cats, which was unthinkable before. But still lots of hissing and growling during the day.

Stress for cat
Since we found our cat was stressed, a behaviourist recommended this food in combination with Bach flower drops. We know our cat was having a really difficult time because she had scratched her neck awfully, and was forced to wear a plastic cone collar. After a week of this food the cone was off and so far she hasn't scratched her neck again. She is part of family life again and is back on my lap for the first time in years. After five years, this was the solution. Awesome right? We only wish we had known about this food earlier, we could have saved a lot of money and stress!

excellent
This summer my cat Baraja suffered a crisis of stress, because in summer we went on a lot of trips and a lot of changes were made in his environment. That made her more shy and she started going to the toilet in odd places around the house. Our veterinarian recommended me this diet and we also used Feliway for a month, and she's already seeming a lot better. Would recommend!

I have a whole different cat
We've had our Stimpy for 6 years now, and she has always been a very scared little girl. She already suffered from bladder stones, but we were also recommended the Royal Canin Calm, and as I said she has changed completely. A cat that you could never previously cuddle will now come and find you for a hug. No sitting on our lap yet but it is a start, and who knows what else this food will do in the future for our Stimpy.

Calmer cat
Our cat Beefy has a habit of hunting my lower legs, and she clearly has a lot of tension in her body at all times! She can be exceptionally grumpy when she's hungry and has had to wait for her meal. Since she's been eating this calm kibble, she's become much calmer and I can even stroke her belly without getting attacked.

Does what it claims
We were introduced to this food when the cats were urine spraying inside and getting into fights. At first we doubted that food could help, but now I'm convinced that the food does what it claims. We no longer see them attacking table legs, and there are barely any fights anymore. Sometimes a little scrap but no huge fights anymore. Apparently it is also delicious, as they gobble it up happily. We have also recently started feeding them half and half with this and the Royal Canin Sterilised food. Really good product!

Excellent
I gave this food to my cats when I moved as a precaution, and we didn't have any episodes of stress or anything weird in the new house. They adapted very well to everything (I also used Feliway), I recommend this food for abrupt changes to your cat's environment, because cats can be very sensitive to them.
