Product details

Royal Canin Veterinary Diet Feline Calm is specially formulated to combat anxiety and reduce the effects of stress on the skin and digestive systems.

How it works

Stressful situations can affect your cat both mentally and physically. This food uses highly digestible proteins which help your cat to process food, reducing the impact of stress on the digestive system. It also contains a special blend of amino acids and vitamins to strengthen the skin barrier, reducing the chance of stress-related skin and fur problems.

Royal Canin Veterinary Diet Feline Calm uses hydrolysed milk protein, which contains a peptide that regulates stress, and L-tryptophan, which can increase serotonin (the happy hormone) levels. Additionally, the combination of fermentable and non-fermentable fibres helps the passage of hairballs while the indigestible fibre assists digestive transit. This reduces the level of hairballs in the cat's stools.

Key benefits

  • reduces impact of stress on digestive system and skin
  • regulates stress levels and increases serotonin
  • highly digestible proteins ease impact on gastric system
  • blend of amino acids and vitamins strengthen the skin barrier
  • fibre combination regulates hairballs
  • nutritionally complete: no need to supplement with other foods.

When to use it

Stress can be triggered by a number of factors, which are usually environmental. Moving house, introducing new pets to the household, or not being allowed outside are all factors that can increase anxiety.  

When cats become stressed they tend to show it in subtle ways. Symptoms differ from animal to animal but usually include changes in grooming, eating and toilet patterns as well as reduced sociability. They may become more aggressive and jumpy, or lose their playful streak. Pica (eating things that aren't food) is another symptom. 

You can relieve stress in cats by making sure there are enough resources (hiding places, water bowls and food bowls) for them: one per cat plus one extra. If they're allowed outside let them choose when to come and go and make sure their environment is stimulating. Your vet will be able to offer more advice if you believe your pet has anxiety.

This food should be fed to cats for two to three months, although it's suitable for life-long feeding in cats with chronic stress. If you anticipate a stressful situation for your cat (such as a house move) you should start them on the diet ten to fourteen days before it happens.

Because veterinary diets are formulated for the nutritional support of pets with specific clinical conditions, we recommend that you only use them under professional advice. For more information on feeding Royal Canin Veterinary Diet Feline Calm to your cat, please consult your veterinary surgeon.

  • Feline calm
    My cat likes the dried food .And helps her stress .
    Shirley Myles - November 27, 2018
  • Excellent results in a very short time
    These biscuits were recommended to me by my vet, as I have a rescue cat who clearly has psychological issues from his time as a stray. We have only been using these biscuits with him for a very short time but have already seen improvements in his nature and hopefully will also help to improve his skin and his overgrooming.

    Royal Canin Calm. We brought this product for some of our long stay guests, they all ate it and seemed to enjoy the food. We used it as part of our tailored approach to caring for the cats staying with us. Some owners with nervous cats have continued to use this product. Trudy Sophisticats Cattery Llanelli
