Royal Canin Calm CC 36 is a complete food for adult cats to be fed every day. It has been specifically formulated to help cats which are in stressful situations. It will help to combat stress-related digestive, skin and urinary manifestations and can be fed as a support for cats undergoing behavioural therapy for anxiety disorders. Anxiety, sleep and appetite will be regulated with L-tryptophan, which is a serotonin precursor. To help your cat maintain a healthy emotional balance, the food contains a combination of Alpha-S1 casein trypsic hydrolysate and tryptophan (an amino acid). The food will also help your cat's digestion and skin, helping to prevent and treat any stress-related problems. Digestive tolerance will be improved with nutrients that help digestive transit and support a balanced intestinal flora. Additionally, the food will help to eliminate hairballs with a blend of fibres which help intestinal transit and the removal of hairballs in stools.

 Royal Canin veterinary dients should only be given in conjunction with your vets recommendation!

Use with prozac

9th Oct 2015

My cat is currently on prozac due to spraying issues (tried all sorts of other solutions first, but nothing worked). Is it ok to feed him this diet whilst on this medication?

This diet should not interact adversely with Prozac or any other similar type of medication.
