Royal Canin Obesity Management is a complete food for adult cats that are obese. It has been specially developed to help reduce body weight in cats that are very overweight. It has low energy density and low calorie levels to help with weight management. To avoid deficiencies, the food also contains plenty of nutrients, vitamins and minerals to ensure that your cat takes in the complete balance that she needs. A high protein content will ensure that muscle mass is maintained despite weight loss. Obese cats have high pressure on their joints and bones due to their large frames. The food will help to maintain strong and healthy bones and joints. Essential fatty acids will help your cat to have healthier skin and a shiny coat.

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

Complete dietetic feed for adult cats.


It is recommended that a veterinarian’s opinion be sought before use or before extending the period of use. Feed Royal Canin Obesity Management until the target body weight is achieved.

Delivery of temperature controlled items

Purchasing any of these items in your order will result in a £1.99 charge being added to the total to cover the high cost of the insulated packaging materials. You only pay the £1.99 once per order, regardless of how many temperature controlled items you purchase in that order.
