What Temperature Is Too Hot For A Cat?

Cats are known to enjoy staying warm. They will lay on a radiator, next to a fire, or in the sunlight. However, there is such a thing as having too much good. Just like any other animal, cats may overheat. What degree of heat is required for something to occur? What temperature is too hot for a cat?

Cats can withstand hotter temperatures because they have greater body temperatures than humans do. However, a cat should not be exposed to temperatures above 100°F.

For both long- and short-haired cat breeds, the ideal temperature range is 75°F and 80°F.

When anything is wrong, cats won’t come right to you. Keep a watchful check on the temperature both indoors and outside to prevent your cat from suffering from heatstroke and dehydration.

How Well Do Cats Handle Hot Weather?

The domestic cat is a descendant of the felis silvestris lybica, an African wildcat. This species, which is still alive, mostly inhabits deserts and other dry environments. As a result, domestic cats have evolved to be able to survive in hot, dry settings and can withstand high temperatures.

But how well do cats handle hot weather? The normal body temperature of a shorthaired cat is 100°F (37.8°C), but longhaired cats have a slightly higher body temperature due to their coat. A cat develops hyperthermia if her body temperature rises above 105° F (40.6° C).

The most serious type of hyperthermia, heatstroke, can be fatal.

How Does Heat and Humidity Affect Cats?

Humidity is just as important as temperature in determining the ideal environment for your cat. Your cat may get dehydrated or heat stroke depending on the humidity level.

To stay cool and control their body temperature, cats have sweat glands. Under normal circumstances, when the perspiration evaporates, the cat’s body loses heat.

This efficient biological system, meanwhile, becomes problematic in very dry or high humidity environments. The cat dehydrates when the surroundings are excessively hot and dry because it loses too much water. However, excessive humidity will prevent the perspiration from evaporating quickly enough.

The index used to assess measures heat and humidity is referred to as wet-bulb temperature. The highest wet-bulb temperature that people can endure is 95 degrees Fahrenheit. If the wet-bulb temperature rises above 90 degrees Fahrenheit, your pet could require cooling down right away.

You may determine the wet-bulb temperature by encasing a thermometer bulb in a moist towel or wet cloth. Alternatively, you might use a calculator that determines the answer using relative humidity and temperature.

What Are the Symptoms of Hyperthermia?

Most cats can tolerate fairly high temperatures, and few cat owners know how to lose weight when their pets get unbearably hot. There is a good chance that our feline friends already have hyperthermia when they start showing the symptoms listed below:

  • Trouble breathing
  • Dark red gums
  • Unexplained aggression or irritability
  • Lethargy
  • Higher heart rate
  • Sweaty paws
  • Body temperature above 105°F
  • Tremor or convulsions
  • Loss of appetite
  • Hot belly and armpits
  • Diarrhea and vomiting
  • Loss of appetite
  • Walking problems

If your cat is a longhaired breed, you should look for signs of dehydration and heatstroke, even if the temperature has not yet reached 100°F.

For example, the Birmans, Maine Coon, or Persian cats, the long-haired breeds, have long coats because they originated in regions with cold evenings or seasonal winters. Intense heat does not suit them. They cannot cool down as quickly as other breeds of cats, as their long coat greatly restricts their sweat glands.

Which Cats Don’t Tolerate Heat Well?

Although most cats can tolerate hotter temperatures than humans, there are some categories of furry cats that are less tolerant of hot weather.


By 4 weeks of age, younger cats can no longer control their body temperature. They rely on their mother to lick and groom them to cool off. Evaporating, saliva cools their bodies.

Senior Cats

The next group is older cats. You can see cat sweat on the pads of the cat’s paws. A senior cat may find it difficult to lick the pads of its feet to cool off due to movement restrictions.

Overweight Cats

Cats with more fat can keep warm longer. Because of their extra weight, indoor cats can have difficulty breathing in warmer temperatures. Compared to healthy weight cats, obese cats tend to have higher body temperatures. This means that it is much more difficult for them to cool down after overheating.

Cats With Health Problems

A cat with respiratory and/or heart disease will find it difficult to get enough air to maintain body temperature.

Also, some short nose cats have breathing problems. They cannot breathe well in hot and humid atmospheres, which causes excessive suffocation and dehydration.

What Is Heat Stroke in Cats?

When a cat’s body temperature exceeds 104 degrees Fahrenheit, heat stroke may occur. Uncontrolled elevated body temperatures can harm a number of your cat’s internal organs. The symptoms of heat stroke, a severe form of hyperthermia, are very similar to those of hyperthermia and include pet vomiting, disorientation, and drooling.

We recommend watching the following video to learn more about what heat stroke is in a cat and what are its symptoms.

You should start the cooling procedure as soon as you have determined that your cat has heatstroke and is not feeling well. When your cat has heatstroke, you can apply the following methods:

  1. Take your cat’s body temperature and write it down to inform the veterinarian.
  2. Provide your cat with fresh cool water. Don’t give your cat ice-cold water because it can constrict the cat’s blood vessels.
  3. Take a spray bottle and spray fresh water around the kitty’s body, or cover the cat with a wet cloth.
  4. Take a towel to dry our cat as soon as the temperature drops to 103.5 degrees Fahrenheit.
  5. Provide a cool surface to relax in (a dark room with no direct sunlight, closed cardboard box, a cooling mat, or any cooler room in the house).
  6. Place a towel-wrapped bottle of frozen or cold water or ice packs next to your cat’s bed or cooling mat.
  7. Be sure to contact and go to the vet.

How Do Cats Cool Themselves Off?

Cats generate heat through sweating, sleeping, grooming, and panting. In some areas of their bodies, cats have sweat glands. The sweat glands, which have the greatest cooling effect, are located on the paws since most of their bodies are covered with fur.

When sleeping, cats may reduce their body temperature. In the heat, cats will also groom themselves more because the saliva that evaporates from their bodies has a cooling effect.

Additionally, when it becomes too hot for the saliva to evaporate off the tongue, they pant.

How to Keep a Cat Cool During Hot Weather?

Cats frequently experience heat stress, which can happen at any time of the year. But it happens more frequently in the summer. To reduce the danger of hyperthermia and heat stroke, it is preferable to keep cats cool and comfortable at all times. Below you will find some simple tips to help you take care of your cat’s health.

Bowl of cool water

The most important thing in hot weather is water. To reduce body temperature more quickly, it is not enough to simply provide fresh water; You also need to make sure it stays clean and cool. It’s a great solution for your cat to provide a cooling bowl which can keep drinking water cool for at least 15 hours.

You can also try giving your cat frozen treats. Frozen treats won’t help cats with heatstroke or prevent them from overheating from extreme hot weather, but they’re a great option to enrich your kitty’s diet and cool them down a bit on a warm day.

Do not leave cats outside or in the car for long periods of time

Cats love to lie in the sun, but because they don’t know what temperature is too hot for cats, they take a risk. Once you’ve given your cats enough time to play and exercise outside, you can bring them inside, away from the summer heat.

On summer days, check the outdoor temperatures before letting your pet outside. In extreme heat, cats, like humans, should avoid direct sunlight.

Never leave a cat in a closed car on a hot day, the temperature in the car will rise very quickly and become too hot for cats in a few minutes.

Provide a cool indoor environment

Especially on hot days with too much moisture in the air, lower the temperature of the air conditioner at home. Generally speaking, the ideal temperature inside a house is between 75 and 78 degrees Fahrenheit. You can also use a fan or vent to keep cats cool and comfortable.

I recommend learning more about air purification and maintaining the correct humidity level – you will find a lot of information on the Air Clean Place resource.

Provide a cool place to rest

The cat must have a place to rest in the cool part of your house. It is desirable that the cat’s bed or house was close to the air conditioner. To allow ventilation, your cat’s bed should be slightly raised. Otherwise, the trapped air underneath will further exacerbate heat exhaustion. During warm weather check the indoor temperature regularly to make sure your cat is not getting too much warmth.

What Temperature Is Too Hot For A Cat? FAQs

Is 90 degrees too hot for cats?

Cats usually feel uncomfortable in temperatures of 90 degrees Fahrenheit and above, requiring additional heat loss through panting. As a general rule, keep your cat indoors if it gets above 80 degrees Fahrenheit outside. Make sure your outdoor cats have access to a shady spot with plenty of fresh cool water, as well as a fan if you have one.

Can cats overheat in 80 degree weather?

To be safe, keep your thermostat set so that when you’re not home, the temperature doesn’t rise over 78 to 80°F. Cats are already at risk when temperatures exceed 80°F; potential problems include sunburn, heat exhaustion, and heat stroke.

Some cats are more vulnerable than others; older cats and cats with pre-existing medical conditions should always be kept cool. Remember that operating a fan by itself won’t be sufficient to keep your cat cool on a hot day.

What temperature is unsafe for cats?

The normal range of outdoor temperature for cats is 45 to 80 degrees Fahrenheit. It is never recommended to keep cats outside when the temperature is below 45 degrees Fahrenheit, especially if they are kittens, older cats, or sick ones.

Cats also cannot tolerate temperatures above 100 F or 38 C. Prolonged exposure to extreme heat can lead to hyperthermia and heat stroke.

Can cats overheat in the house?

Yes, for sure. Even indoors can be too hot for cats. Depending on the cat’s lifestyle and other circumstances, the exact temperature tolerance may differ from one cat to another. Humidity can also affect overheating.

How Do You Check a Cat’s Body Temperature?

An average body temperature of a healthy cat is 101.0 to 102.5°F (38.3 to 39.2°C). Utilizing a thermometer is the simplest technique to determine our cat’s temperature. In the absence of a thermometer, there are other techniques to determine if a cat is under heat stress.

How do you use a thermometer to check your cat’s temperature? Follow these steps:

  1. To restrain aggressive behavior, place a blanket over your cat. Otherwise, you may need another person to help you.
  2. Use a rectal thermometer to measure temperature.
  3. Use lubricant. Gently place the thermometer in your cat’s anus.
  4. For a more accurate measurement, leave it there for a few minutes.
  5. Carefully remove the thermometer and record the reading before cleaning.

If you don’t have a thermometer, there are other ways to detect high body temperatures.

  1. Check the humidity of your cat’s nose. Dryness indicates dehydration, and even overheating.
  2. Check your ear temperature. A cat’s ears often feel warm. The difference in heating when overheating is really noticeable.
  3. Overheating is indicated by a body that is warmer than usual. Make sure he hasn’t just woken up from a warm sleep.


Both outdoor and indoor cats can be affected by heat. When temperatures get too hot for cats, your pet needs special attention and care. If indoor temperatures rise above 80 degrees, provide your cat with cool places to rest.

Remember, a warm cat is good, but if the cat’s body heat rises, it can lead to hyperthermia. You need to know the average body temperature of a healthy cat and make sure that your kitty’s body heat is within the normal range. The average cat has a body temperature of 101.0 to 102.5°F. And please contact your veterinarian immediately if you suspect that your cat has hyperthermia!

I wish you and your cat joyful and happy summer days!
