You may notice that your appetite can go down as the weather heats up, but is this the same for cats? In this guide, we delve into whether cats eat less in summer and give advice on how to keep your cat healthy when it’s hot.
A study by the University of Liverpool School of Veterinary Science found that cats eat around 15% less in summer than in winter. [1]. The study, conducted over four years, involved monitoring the feeding habits of 38 cats, and it was found that their food intake increased in winter and decreased in summer.
A change in appetite when it’s hot is thought to be linked to a drop in energy levels. When it’s hot, cats are inclined to laze around more, so they’re not using as much energy as when they’re playing, hunting, or roaming their neighbourhood. So, as they’re less active, they don’t need as much food [3]. And, cats don’t need to use as much energy keeping warm in summer, so they need less calories [4].

Yes, the research by the University of Liverpool shows that cats can eat less when it’s hot. However, if your cat hasn’t eaten anything in 24 to 48 hours, you should get them checked by a vet in case there is something medical going on that has caused them to lose their appetite.
Even though your cat may want to eat less when it’s hot you should still put food down for them, in case they are hungry. It’s also important they have access to water to stay hydrated. Some cats can be suspicious of water (it’s a natural survival instinct from their wild ancestors), so feeding them a raw diet high in moisture is an excellent way to ensure they get the water intake they need.
The heat can make us behave differently, but what about our cats? Well, a study has recorded that extreme hot weather can affect cat behaviour making them less active, less willing to play, and some cats showed an increase in fear behaviour particularly in response to summer thunderstorms and heavy rain [2].
Understanding how to keep your cat cool in summer may support their behaviour so they don’t find the heat too difficult to deal with.
Firstly, if you can, feed them a species-appropriate, complete, and balanced diet so they are getting the nutrients they need in the right amounts. Also, make sure your cat has:
Heatstroke in cats can be fatal, so it’s important to follow this advice and keep your cats cool.
If you think your cat isn’t eating enough, you can try adding toppers to their meals to make them more enticing. We know from our customers that their cats can’t resist Magic Sprinkles – freeze-dried pieces of chicken that you can sprinkle on top of your cat’s regular food. Bone broth is also another favourite with cats – available in lamb and beef, it’s full of aroma, taste, and natural nutrients. A 3-way winner!
Also, natural food toppers like sardines are a huge hit with cats.
If you’re concerned your healthy cat is losing weight, please consult with a vet to check if there is anything medical causing it.
Changing how you split out your cat’s total amount of food per day so they have smaller, more frequent meals may be better suited to their feeding needs in summer. For example, instead of feeding them twice a day, give them 3 meals instead. However, keep in mind that cat’s are suspicious of change, particularly around food, so they may wonder what is going on!
A cat’s weight shouldn’t change if they’re eating less and moving less. However, if your cat isn’t eating, is lethargic, is losing weight, or you have concerns about your cat’s health generally, you should consult a vet to determine the cause.
Research by the University of Liverpool School of Veterinary Science shows that cats eat more in winter than summer [1]. This can be due to cats needing more energy to keep warm or the fact that cats are more active in the cooler months [2].
You should continue to provide your cat with their regular species-appropriate, complete, and balanced meals, as this gives the nutrients your cat needs. Additionally, you can add some bone broth to their meals to entice them to eat. Or, adding natural food toppers like sardines.
Keep in mind, the reason your cat may be eating less of the food you provide them, is because they may be eating wild prey.
If your healthy cat has eaten anything for 24 to 48 hours you should consult with a vet as there may be a medical issue that is keeping them from eating. For instance, they may have a dental issue which is preventing them eating or they may have an injury that is causing them pain. Environmental changes, like a new pet in the home, or a change of feeding bowl, can cause anxiety in cats which can lead to a loss of appetite.
Yes, the heat can make cats more tired.
Research has shown that some cats are less active in the hotter summer months [2].
Cats love their sleep, but on hotter days you’ll probably find your cat sleeping more.
If your cat is hot, they will take themselves off to a shaded place to cool down, such as a cool room or shaded outdoor spot. You may notice that your cat is less active and prefers to laze around more. Your cat may also increase its grooming as a way to cool itself down.
Please note, if your cat is panting, this is a sign of advanced heatstroke. It’s crucial to seek veterinary help immediately to ensure your cat’s well-being.
There isn’t a definite temperature to say that it’s too hot for your cat. However, the general rule of thumb is, if you find it too hot, it’s probably too hot for your cat.
Each cat is an individual and has their own unique way to lie down, however, most prefer to lie on their side when it’s hot.
Cats are attuned to their environment and will be able to know when they’re getting too hot. They may take themselves off to a shady spot or groom themselves to cool down.
Yes, a cat’s appetite can fluctuate due to a number of reasons, including:
It could be that your cat has less of an appetite due to the warmer weather. If your cat hasn’t eaten anything for 24 to 48 hours, please consult a vet to see if anything medical is causing them not to eat.
Some cats will happily eat the same thing day in and day out. Others will get bored of the same meals. It all depends on your cat. If your cat is ‘becoming fussy’ with their food, they could be bored of it. Try introducing new flavours, but do it slowly in case of allergies or intolerances. You can also try adding toppers to their meals to change the consistency and up the flavour.
If you notice that your cat is eating less in summer, it doesn’t have to be a cause of concern. That’s unless your cat hasn’t eaten anything for 24 to 48 hours, in which case you should consult a vet.
