Cats are not naturally built to withstand high temperatures, and in fact, most breeds of cats come from places with cooler climates. For this reason, it’s not surprising that many cats tend to lose weight in the summer.

There are a few reasons why this happens. First of all, cats generally don’t drink as much water as they should when it’s hot outside. This is because they don’t sweat like humans do, so they don’t have the same urges to drink frequently. As a result, they can become dehydrated quickly.

Secondly, cats may not eat as much when it’s hot because their appetites can decrease in the heat. This is particularly true if they’re not used to the heat and are finding it difficult to adjust.

Finally, some cats simply move less in the summer months because they don’t want to exert themselves in the heat. This means they burn fewer calories and can lose weight as a result.

If you’re concerned about your cat’s weight loss in the summer, there are a few things you can do to help them stay healthy. Make sure they have plenty of fresh water to drink and try to feed them smaller meals more often throughout the day instead of one large meal. You can also try moving their food bowl to a cooler location in your home or placing a fan near their eating area. And if possible, make sure they have access to shade or air conditioning when it’s very hot outside.

The Science Behind It

There are a few reasons that cats may lose weight in the summer. The most common reason is that they are expending more energy in the warmer weather and burning more calories. Outdoor cats also have more opportunities to hunt and eat small prey, which can help them maintain their weight. Additionally, some cats may lose weight due to health problems, such as diabetes or gastrointestinal issues.

How to Help Your Cat Lose Weight

Cats, like all animals, are more active in the summer. This means they burn more calories and can lose weight. If your cat is already at a healthy weight, there is no need to worry. But if your cat is overweight or obese, you should take steps to help them lose weight.

There are a few things you can do to help your cat lose weight:

-Feed them smaller meals more often. This will help them feel fuller without eating as much.
-Increase their activity level. Play with them more often, or get them a scratching post or climbing tree to encourage them to move around more.
-Choose lower calorie foods. Look for foods that are specifically designed for cats that need to lose weight. These foods have fewer calories but are still nutritionally complete.
-Talk to your vet. They can help you come up with a plan to help your cat lose weight safely and effectively.


In conclusion, cats may lose weight in the summer due to less food intake and more physical activity. However, if your cat is not eating or drinking enough water, please consult your veterinarian.
