Summer’s just around the corner, and that means more sunshine, longer days… and for many cats, a little less exercise. While we might be busy making summer plans – or even working on our own summer body – your cat is probably just chilling in the sun. But is that really so harmless? Cats tend to move less during the warmer months. They nap more often, lounge in the shade, and as a result, can gain weight more quickly.In this blog, you’ll find out how to spot the signs that your cat might be carrying a few extra grams, why that can be a problem, and what you can do to help your fluffy companion stay fit and healthy all summer long. 

Your cat might not be going on a crash diet for the beach, but their little tummy does wobble a bit when they walk

Is my cat just fluffy… or actually a little chubby?

Some cat breeds, like the Siberian or the British Shorthair, naturally have thick coats. But that can make it tricky to tell whether your cat is just fluffy… or actually overweight.

Not sure? We've got a simple checklist for you:

❌ Can you barely feel their ribs? Then there's likely a layer of fat over them.

❌ Is their belly a bit round or sagging? That’s not just cute — it could be a sign.

❌ Are they jumping or running less than they used to? Extra weight might literally be holding them back.

Of course, a visit to the vet will give you clarity. However, your own observations are often a great first step.

With cats, every gram counts: 500 grams of excess weight on your cat is roughly equivalent to 7 kilos on a human

Overweight: the silent danger hiding beneath all the fluff

A little extra weight might seem harmless, but for cats, it can quickly become harmful. They’re small, move less, and can’t express their discomfort in words.

Risks of excess weight in cats include:

  • Diabetes
  • Joint problems & reduced mobility
  • Heart & liver issues
  • Reduced grooming (which can lead to skin problems)

⚠️ Please remember: cats should never lose a lot of weight all at once. A crash diet can lead to serious liver issues. It’s all about gradual, steady change — slow and safe wins the race when it comes to feline weight loss.

Just like us, cats are more prone to feeling the heat during the summer. Any extra activity should be playful and gentle — never forced

5 Simple things you start with today

Good news: it doesn’t have to be a big change. These simple tips can already make a small difference:

  • Portion control – Use a measuring scoop and adjust the amount of food based on your cat’s weight and age.
  • Easily digestible food – Choose low-fat food, specially formulated for neutered or indoor cats. Think chicken or turkey-based meals, with added fibre like psyllium or beet pulp for healthy digestion.
  • Short play sessions throughout the day – It’s better to play actively for 5 minutes, 2–3 times a day, than one long session. Think laser pointer, feather wand, or even chasing a scrunched-up bit of paper.
  • Smart snacking – Swap treats for a few kibbles taken from their daily food allowance, or use food puzzles.
  • Hide some snacks – Let your cat “work” for their food by hiding it in a cardboard box or a snuffle mat.

💡If you're unsure, feel free to ask your vet for advice – they’ll be happy to help you find what’s best for your cat.

Bonus: give him more climbing options
