Do cats sweat? How to tell if your cat is overheated

Here's how cats cool off when they are too warm

By

Between their love for sleeping in sunbeams and their penchant for naps in front of the fire, cats gravitate toward warmth. Given their ability to withstand temperatures that leave us sweaty and miserable, it stands to reason that staying cool isn’t a problem for cats. As it turns out, that’s not the case at all. Just like humans, cats need to regulate their body temperature, especially during the hot months. However, unlike humans, cats take a slightly different approach to staying cool.

Here’s how cats stay cool — and the signs you need to look out for that could mean they’re in trouble and require treatment for heat-related conditions.

Do cats sweat?

Technically, cats do sweat, but not the same way that humans do. As humans, we sweat all over our bodies, but cats have much more limited sweating capabilities. Humans have sweat glands located just about everywhere, but cats have sweat glands only in a few areas that lack hair. These areas include your cat’s paws and chin, so your cat can sweat only in those particular areas. (This is true also for dogs.)

As your cat sweats, air that moves over the sweat helps cool his body. Because sweating capabilities are so limited for cats, sweating is a secondary cooling system. Your cat has other ways to help regulate his temperature and cool off.

How do cats cool down?

Rather than relying on sweating to help cool down, cats get rid of body heat by grooming. Evaporating saliva works just like evaporating sweat to cool the skin. So, you might see your cat groom himself more often when it’s warm out, particularly when he’s lying in a hot, sunny spot.

Speaking of lying around in the heat, cats take naps during the hot days to avoid some of the heat. By limiting their activity during the daylight hours when it’s hot out, they can stay cooler. As the temperatures drop in the late afternoon and evening, cats become more active with hunting, eating, and playing.

Cats instinctively know to seek out cooler spots when things heat up during the day. You might notice that your cat heads to the basement or lies on the cool tile floor during hotter days. It’s just one of the ways that he’s regulating his temperature and staying cool.

Signs your cat is overheating

These are the signs your cat might be overheated:

  • Panting: If your cat’s other methods of temperature regulation aren’t enough, he may start to pant. Cats don’t typically pant, and this is a sign that your cat may be stressed or overheating.
  • Heat stress: If the problem progresses, your cat may experience heat stress. Common signs of heat stress include drooling, excessive grooming, and sweaty paws. Your cat may act aggravated or restless as he looks for a cooler area.
  • Heat exhaustion: Heat exhaustion can occur if your cat can’t lower his body temperature. Signs of heat exhaustion include rapid breathing, a red tongue and mouth, stumbling or uncoordinated movements, lethargy, and vomiting. Heat exhaustion is a life-threatening emergency that needs to receive appropriate treatment immediately.

If you notice signs of heat stress, move your cat to a cool area and call your vet. And if you think your cat is experiencing heat exhaustion, then put cool water over his body and call your vet immediately. If you can’t reach your vet, take your cat right to the nearest emergency clinic. A vet will probably administer cool fluids and monitor your cat’s body temperature. Heat exhaustion can lead to organ failure, so professional treatment is essential.

In most situations, your cat can regulate his own body temperature just fine. Cats instinctively know how to keep themselves cool, and most won’t expose themselves to extreme temperatures that could lead to heat stress or exhaustion. However, it’s still possible for these medical emergencies to occur, especially in cats who are exposed to extreme temperatures or suffering from other medical issues. Being aware of the signs of heat stress and heat exhaustion can help you quickly identify these conditions if they occur. Knowing the right steps to take to promptly get your cat medical help can help save his life in these situations.

Why do cats hate closed doors?

When you go to the bathroom and shut the door, you might instantly hear the sounds of a cat positively shredding the outside (see also velcro dogs). It's not just that they want desperately to be near you, though. Cats have a unique perspective on their own space and a need to control it. After all, your house is theirs, too.

Cats can get the reputation of being perpetually grumpy and unloving. These are myths — cats can be playful and remain affectionate even after the kitten stage.

Yet, cats — like humans — experience various emotions, including anger. Even the cuddliest, most mild-mannered kitties have their triggers and moments. Unlike humans, cats can't tell you how they feel using words. Though cats can vocalize — and often will when angry — watching body language will provide the most clues into what your cat thinks about their current situation.
