Although pudgy cats may seem cute and cuddly, being overweight can have a significant negative impact on your cat's health and longevity. Carrying extra weight puts strain on your feline friend's joints, makes them prone to conditions like diabetes and fatty liver disease, and ultimately shortens their lifespan.

Helping your cat lose weight may seem like a difficult task at first, but it is one of the best things you can do to keep them enjoying a happier, healthier and longer life. Remember that all good things take time, and weight loss in cats is no different. Most weight loss programs for cats aim for a loss of about 0.5% to 1% per week, so even a loss of 25g a week for a 5kg cat can be step in the right direction!

We all want our cats to live long and happy lives, so what can you do if you think yours might be overweight? To help you get started, we've written a helpful guide with tips on diet, exercise, and more!

Is your cat overweight?

Sometimes a fluffy coat can mask the secret pudge underneath, however signs your cat could be overweight include:

Sagging belly
Large 'pouch' under abdomen
Loss of obvious waist
Unable to feel ribs
Reduced activity and sleeping more

Body Condition Scoring your cat is a simple way to assess if they are overweight, and more accurately reflects the amount of fat coverage than the number on the scales. Have a go at performing a body condition score on your cat at home using our Body Condition Score Chart. A cat at an ideal body weight will have a body condition score of 4 or 5 (out of 9), and if your cat scores a 6 or more, then some weight loss would be beneficial. Your treating vet will be able to confirm your cat's body condition score for you.

Talk to your vet about the right diet

If you think that your cat may be overweight, you should seek advice from your veterinarian. They may recommend a special prescription diet like Hill's Metabolic Weight Management or Royal Canin Satiety as part of a weight loss program. It is important to remember that prescription diets are only used under the direct instruction of your pet's veterinarian.

When feeding a weight loss diet it is crucial to stick to the amount recommended by your veterinarian. Even an extra ten pieces of kibble a day can cause a cat to gain an extra half a kilo of fat over a year!

Tip: Wet food is less calorie dense than dry food due to its high water content, and can help with weight loss by increasing the volume of food your cat is eating without increasing the calories!

Best weight loss diets for cats

Encourage activity

Increasing your cat's activity will help to burn off some of their energy and kick-start their metabolism. Schedule in at least two 10 minute play sessions with them every day. Not only will your cat benefit from getting moving, but they will love the one-on-one time with you! Make sure to have plenty of interactive toys around to help keep them moving, and you can even teach them to walk on a lead to burn some calories whilst exploring the great outdoors!

Best cat toys to encourage activity

Start forage feeding

If your cat is constantly begging for food and then gobbles up their meal in 5 seconds, you may want to reconsider your feeding method. Using a puzzle feeder is a great way to help slow down your cat's speed of eating and help them feel fuller for longer. These toys also help to keep your cat mentally stimulated and physically active.

Treat the right way

Even a small amount of treats can send your cat's weight loss program off the rails. But that doesn't mean your kitty cat has to miss out on their favourite nibblets. There are plenty of ways to 'treat' your cat without adding to their calorie load.

Kibble for Thought

As an alternative to high calorie treats or human food, you could set aside a few of your cat's kibble every day as a 'treat ration' or use non-food rewards like a scratch behind the ear or some extra playtime.

Add Fibre to the Diet

If you cat still seems hungry, you can trick their tummy into feeling 'full' by adding a little extra fibre to their food. This helps 'plump' up the meal and leaves them feeling fuller and more satisfied. You can feed them some soft, mushy cooked zucchini or sprinkle some natural, unflavoured psyllium husk onto their food.

Low Fat Cat Treats

Of course, you might also like to purchase some tasty low-calorie treats. Our top suggestions include: Greenies and Prime100 Pantry Nibbles.

Avoid Human Foods

Be especially careful of human food, as the calorie load is a lot more significant to your cat's tiny body. For example, 1 cup of milk might not seem like much to us, but for a 5 kg cat 1 cup of whole milk is the equivalent of three hamburgers to an average sized woman!
