Product details

Help your cat lose weight and achieve a healthy size with Royal Canin Veterinary Diet Feline Obesity DP 42.

How it works

Royal Canin Veterinary Diet Feline Obesity DP 42 is specially formulated to help shift your cat's excess pounds and have it looking sleek again. This is a dietetic feed that's specifically designed to help combat obesity in adult cats, and it works by combining high amounts of proteins contained in poultry, cereals and eggs, with all the vital nutrients and minerals your cat needs to maintain its health. It's also low in starch and packed with vitamins so your cat won't lose out on anything it needs. Essential fatty acids have also been added to the feed, which help keep your cat's skin healthy and maintain a rich, shiny coat.

Key benefits

  • a complete feed developed to help cats slim down
  • specially selected nutrients to support joints stressed by excess weight
  • comes in wet and dry versions to cater for your cat's preference
  • great taste that cats love.

When to use it

Many cats suffer from obesity. In fact it's estimated that it affects up to 30% of cats in the UK alone. If your cat has noticeably grown in size, seems sluggish or has trouble moving, it may be overweight. This can not only greatly reduce its quality of life but also give rise to conditions such as diabetes and stressed joints caused by carrying too much weight. By acting early and contacting your vet at the first sign of symptoms, you can stop these potentially painful conditions from developing. 

Your vet may advise you to put your cat on a specialist diet. In this case, Royal Canin Veterinary Diet Feline Obesity DP 42, which is approved by vets, could be the ideal choice to get your cat back to its ideal weight and have it feeling and looking healthy again.

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 Obesity DP 42 to your cat, please consult your veterinary surgeon.

  • My fat cat loves these
    Buddy loves these biscuits - probably too much, as he is still quite fat. But I think he is losing a bit of weight, definitely looking a bit more slim line &Belly not hanging too much now!!!

  • it is working
    Excellent weight loss product. The cat has lost over a kilo to the vets delight. The cat is happier and so is the vet. Now to keep the weight off, so continuing to feed this kibble. I would very much recommend this to help with weight loss in cats as it has worked for my cat.
