PURINA® PRO PLAN® VETERINARY DIETS Feline OM ST/OX Obesity Management Wet Food with Chicken is clinically proven to help nutritionally manage obesity and maintain an optimal weight in adult cats. It is low in fat and calories whilst being high in protein to encourage steady and effective weight loss, all the while maintaining muscle mass.

Made with high levels of natural fibre and protein, it will help your cat feel full and satisfied. It is also highly palatable to help make losing weight easier and once the ideal weight is reached, your cat can stay on this formula to help keep the weight off.

Key benefits:  

  • High protein to help promote loss of body fat whilst maintaining lean muscles during weight loss
  • Low calorie: reduced levels of fat to help reduce the number of calories consumed and promote effective and steady weight loss.
  • Promotes healthy urine composition to help minimise the development of urinary crystals and stones, which are more common in overweight and obese cats

Please note: It is not recommended for cats that need a higher calorie intake such as pregnant queens or growing kittens.


Fresh drinking water should always be available.
