Cats love summer, but sometimes it’s just too hot. Learn how to cool down a cat so that you can keep them safe in the blistering sun. How to keep a cat cool in summer? As the weather warms up, you might notice your cat’s behaviour starting to change a little. Whether your cat is indoor, outdoor, or a combination of both, they can struggle with hot weather, just like you do.

If you are lucky enough to have air conditioning, you can control the temperature of your home, but if you don’t or if your cat loves to explore the neighbourhood, then you may need to find other ways to help keep your cat cool.

 

How Hot is Too Hot for Cats?

Cats often prefer warm weather, opting to bask in a sunbeam or lie on the windowsill. Some cats act borderline cold-blooded in the way they seek out heat sources, so it's no surprise that warmer temperatures don't seem to faze them.

Though modern cats are living the life of Riley in our air-conditioned homes, their ancestors were accustomed to hot, arid climates. This likely contributes to your cat's natural affinity for finding the warmest, sunniest spot in the house.

But there is a limit to how hot they can tolerate before it loses its appeal and becomes uncomfortable. Here are some general guidelines:

    • Indoor temperatures above 28°C can start to be uncomfortable for your cat, especially without proper ventilation or air flow. Cats in these conditions will be less active and may even eat less to conserve energy.
    • Outdoor cats can suffer in extreme heat, too. Direct exposure to the sun and hot surfaces can make warm weather feel even hotter, so limiting outdoor access when the outdoor temperature is above 28°C may be necessary to keep them safe.

The temperature isn't always going to be in our control, which is why it's important to keep reading to find out all the best tips for how to keep your cat cool in the summer.

 

 

How Cats Cool Themselves

Cats are naturally equipped to control their body temperature effectively under normal conditions. From their naturally insulating coat to their ability to make slight behavioural changes to conserve energy, cats can often keep themselves safe in warm conditions.

Here’s how they do it:

Panting

Like dogs, cats pant to cool themselves. Panting allows cool air to circulate in their respiratory system, which helps to expel heat. Panting in cats is not as animated and obvious as it is in dogs, so you might not notice your cat panting unless they are extremely overheated.

Excessive panting means that they are struggling to control their temperature, and you need to intervene.

Sweating

Cats sweat through their paws like dogs. Sweat facilitates heat removal from the body as the moisture from the sweat evaporates. It’s rare that you’ll notice super-sweaty cat feet, but this, in combination with panting, is your cat’s involuntary method of cooling down.

Grooming

This one is pretty unique to cats, but grooming is actually another method of cooling down. When grooming, cats leave behind a little moisture, and like sweat, the moisture from their saliva helps to draw heat out of their body as it evaporates. 

These basic practices will help your cat maintain a comfortable body temperature to an extent. External factors like humidity, temperature, direct exposure to the sun, and air flow can all be factors in how well your cat can keep themselves cool.

 

Signs of Cat Overheating 

Cats prefer to hide their discomfort, so it’s not always easy to notice that they are struggling with the heat. There are a lot of things that you can do to keep your cat cool and comfortable, but being able to recognize signs that your cat is overheating is a matter of safety. 

Minor changes to demeanour are normal as seasons change, but you should be on the lookout for behaviours that are dangerous, destructive, and out of the ordinary. Here are some things you might notice if your cat is too hot:

Lethargy

Cats may act very low-energy if they are too hot. This doesn’t necessarily mean they are dangerously hot, or even overly uncomfortable, but it is their natural way of limiting energy output to keep their body temperature low.

An overheating cat will also show lethargic behaviours. This could be the beginning stages of heatstroke or dehydration. This is why lethargy should always be taken seriously and should prompt you to look for other possible symptoms that may indicate that you need to intervene.

Agitation

Sometimes, cats that are feeling the effects of a hot summer day may act agitated or even aggressive. This could present in a serious case of the zoomies, destructive behaviours like scratching or chewing or picking fights with other pets or you, or just general restlessness.

Agitated behaviours are not enough to make a determination, but if your cat is abnormally upset or on edge, it’s important to take note.

Loss of Appetite

Cats can be very particular about eating routines, so a skipped meal here and there may not surprise you, but if your cat is refusing to eat at all, then you might want to consider this a sign that they are feeling the effects of overheating. 

Overheating, heatstroke, and general discomfort from the heat can all cause your pet to turn their nose up at food. Monitor how often and how much they are eating, and try to encourage frequent small meals to get your cat the calories and nutrients they need to stay healthy.

Seeking Cool Surfaces

If you keep finding your cat lying on the tile floor of the bathroom, or the hard concrete of your basement or garage, then it’s very likely she is seeking out cooler surfaces to help reduce her discomfort.

Cats love air conditioners, too. It’s common for them to plant themselves right in front of an air conditioner, a fan, or an open window just to feel the cool stream of air. If your house is on the warm side, it’s not a bad idea to make sure these devices are safely positioned for your cat to enjoy them.

Panting

If you are a dog owner, you know that panting is a normal way for dogs to release heat from their body, but what about cats? Why do cats pant when hot? If you notice your cat panting like a dog, then you should be concerned.

Cats pant for the same reasons that dogs do, but not as often and typically not as hard. Normally, you might see your cat gently panting after a high-energy round with a cat wand or fetch or after a case of the zoomies, but panting during low-energy activities could mean your cat is cooking. We’ll dive more into cat panting later in this article.

Drooling

If you have a cat that drools when they purr, then you might not see this as abnormal behaviour, but excessive drooling, or drooling in unusual situations, can be a bad sign. This is especially telling if it’s combined with panting or other behaviours from this list.

Vomiting

Throwing up is not the most uncommon thing for cats. Many cats deal with hairballs and are no strangers to regurgitating food after meals. Though the reasons can vary, vomiting alongside panting, drooling, or lethargy is concerning.

 

Consequences of Cat Overheating

If you're dealing with a prolonged heatwave, then your cat will probably show mild symptoms of overheating, but if the symptoms don’t go away or start to worsen, then your cat could be in danger.

Two things could result from prolonged overheating:

Dehydration in Cats

Cats are not naturally drawn to water, so unless they are eating a moisture-rich diet, most average house cats live in a perpetual state of mild dehydration already. Further dehydration can cause many problems, and overheating will quickly dehydrate your kitty even further.

The even tougher aspect of dehydration in cats as a result of overheating is that you can lead a cat to water, but you can’t make them drink. It may be necessary to encourage moisture intake through food or tasty water additives.

In cases of extreme dehydration, your cat will need an IV to replenish their fluids, so don’t wait to call your vet if you notice signs of dehydration in your cat.

 

Cat Heatstroke

Cats typically have a body temperature of between 100 and 102 degrees F. If your cat’s body temperature goes above 103, then your cat is overheating, but over 106 is an emergency. This means your cat has heatstroke.

Heatstroke causes your kitty’s organs to start shutting down, so it’s vital that you act quickly and seek medical attention to lower your pet’s body temperature safely. In addition to the signs of overheating above, you may also see either brightly coloured or very pale gums.

If you suspect heatstroke, call your vet immediately. Heatstroke can easily be life-threatening if not treated in a timely manner. Contact your vet for instructions on how to try to lower their body temperature and prepare them for transport to the vet safely.

Cats That Are Most Susceptible to Overheating

While any cat can feel the effects of extreme temperatures, some cats are more susceptible than others. Here are a few examples of cats at high risk of overheating and heatstroke:

    • Senior cats
    • Sick Cats
    • Overweight Cats
    • Cats with thick fur
    • Brachycephalic breeds (short noses or squished faces)
    • Young kittens
    • Hairless breeds
    • Outdoor cats

If your cat falls into one of these categories, you should consider a more controlled environment to keep them safe. Keep them inside if you have air conditioning, provide fans, and keep windows open to provide a cross-flow of cool air in your home. Keep reading to find out more ways to cool your cat down.

 

Cooling Down a Hot Cat 

Keeping your cat cool and comfortable when the weather is hot will help keep them safe. Preventing overheating is easier than treating it, so whenever the temp feels a little too warm for you, you should act as if it’s too warm for your cat, too.

There are several factors involved in deciding how to keep your cat cool, the first being the environment. There is a difference between indoor and outdoor cats. Their behaviours and ability to control their own body temperature will be different because of their environment.

10 Tips for Cooling Down an Indoor Cat

Indoor cats have an easier time maintaining control over their body temperature because they are more likely to be able to escape the sun and have access to fresh, cool water. While there are advantages for indoor cats, your cat may still need some additional help beating the heat. Here are some simple ways to cool down your indoor cat:

1. Keep Them Hydrated

Incorporate more liquids into their daily routine. Multiple water sources, like cat water fountains, will help to encourage your kitty to drink more. Additionally, feeding a higher moisture diet, like raw cat food or canned foods, will help to replenish moisture regularly.

Other options like bone broth or goat’s milk can be added to dry foods or fed as treats to help increase your cat’s daily moisture intake.

2. Provide Cool Spaces

As we said earlier, your cat might seek out cool surfaces, like tile or concrete, to help cool them. Try to leave your cat with safe access to these cooling methods, even if you are not home. This might mean leaving bathroom doors open or giving your cat access to your basement.

3. Air Circulation

Set up cat trees or chairs in the path of fans or air conditioners. This will give your cat a safe spot to literally chill. If you don’t give them easy access, they may risk climbing furniture or exploring dangerous platforms just to get closer to the cooler breeze.

4. Cold Treats

Frozen treats are popular for dogs, but cats are more particular about temperature. You are better off offering them a cool, moist treat. Our favourites are whole raw sardines or chicken necks from Big Country Raw.

5. Cooling Gear

Lots of cooling gear is designed for dogs, but that doesn’t mean that it can be used for cats, too. Cats are typically less happy about wearing clothes, but you don’t have to give them a full cooling vest. You can start with a simple cooling bandana.

Cooling mats are a popular option among dogs, but are not always recommended for cats because they often use gel beads to keep cool. These gel beads are toxic if ingested, and because cats like to knead their beds, there is a high possibility that they will split the material, exposing the toxic gel.

6. Limit Sun Exposure

Keep your curtains closed to limit direct sun exposure. Cats love a good sunbeam to lie in, but on the hottest days of the year, you may have to limit how much sunbathing your kitty does. This goes for outdoor cats, too. Keep them in areas that provide shade and shelter from the sun.

7. Keep Them Indoors

Even though your cat may love spending time outdoors, when the temperature outside gets crazy, it may be safest to keep them inside until the weather breaks. They may not be happy about this, but it’s about keeping them safe.

8. Keep Calm

Your cat may be anxious or restless, but too many activities will not help them keep their cool. Limit playtime to lower-energy activities to keep your pet calmer and relaxed. Stick to couch cuddles and belly rubs instead.

9. Raised Beds

Beds or cat trees that are raised off the ground, like The BeOneBreed Ladder Cat Tree with Scratcher, may not seem all that special, but in reality, the airflow under the bed will help to keep them cooler than in a bed that is directly on the floor. Set up this bed near a fan to push cool air under and around the bed.

10. Damp Cloth

If sweating and grooming help your cat cool using evaporation, then you can help them speed up the process by giving them a quick rub down with a damp cloth or towel. They may not love being wet, but they will be able to cool down faster. This is a great option if your cat won’t tolerate cooling gear.

Bonus Tip: Go for Swim

We added this one just for fun. If you read this and thought - WHAT ARE YOU INSANE!?!, then you are not alone, but don’t knock it till you try it. There are cats who don’t mind water, especially if they are looking for a way to cool down. 

Most can actually swim. They also just choose not to. Some cat breeds are more likely to have an affinity for water, like Maine Coons, Bengals, and Turkish Vans, but don't expect your indoor cats to be thrilled to dive in.

Most domesticated cats have never had any experience with swimming, so the experience can be quite stressful. It will take time and practice to get your cat comfortable around water, and frankly, some cats will never go for it. Forcing them will only increase fear and anxiety.

 

How to Keep Outdoor Cats Cool During Summer

If your cat loves to spend most of her days exploring the neighbourhood, then you may need to consider additional measures to keep them cool. Beyond the tips above, like cooling gear, there are additional things you can do to ensure that your cat can safely enjoy a hot summer day. 

Provide Water

Even if your cat doesn’t love water, leaving out a large bowl of fresh, clean water will ensure that your cat will know where to come to rehydrate or even cool down if she chooses to dip her paws in. Your cat’s survival instincts will tell her to find water if she needs it.

Feed High-Moisture Food

Cats don't always drink as much water as they should, even on hotter days, so offering wet cat food, raw cat food, or other moisture-rich meal toppers can help ensure they are properly hydrated

Provide Shelter

Your cat is going to explore as she pleases, but that doesn’t mean that she won’t need a reprieve from the beating sun. Providing an insulated shelter, like a dog house, will help her get out of the sun and control her body temperature. 

Limit Outdoor Time

This may not be an option that your cat appreciates, but it is in her best interest to keep her inside during the hottest parts of the day. Change her outdoor time to early in the day or in the evening when the sun isn’t as hot.

 

It’s a Hot Cat Summer

Now that you know how to keep cats cool, you and your kitty can enjoy your favourite summer activities. Whether you are relaxing at home, playing in the yard, or going on exciting adventures with your feline companion, these tips for keeping your cat cool can help. 

Just remember to look for the signs of overheating, be aware of the environment your cat is in, and choose the tips for cooling down your cat that work best for you. 

If you are ever concerned about your cat's temperature, it’s always best to connect with your vet. Prevention is always better than treatment, and your vet can help you determine if your cat has any health issues that may put her at a higher risk of overheating.
