how hot is too hot for cats

If you’re a cat owner, you know that felines are sensitive creatures, including their reaction to temperature changes. Any temperature above 100°F is too hot for a cat’s comfort. Knowing how hot is too hot for cats can help you protect them from heat-related illnesses.

In this guide, we’ll talk about the best temperature range for cats; outdoor, indoor cats and hot weather, and how to tell if they’re getting too hot so that your furry friend stays healthy and happy during the warmer months.


Optimal Temperature Range for Cats


How hot can cats handle? Knowing the ideal temperature range for cats can assist cat owners in taking the necessary measures to keep their pets comfortable and avoid heat-related health issues such as dehydration and heat stroke.

So let’s discover all the detailed information about the appropriate indoor and outdoor temperatures for cats right here.

1. What is the best indoor temperature for cats?


The ideal room temperature for cats may vary depending on their age, breed, and health condition. However, the range of 69-72°F (20-22°C) is considered comfortable for indoor and outdoor cats.

This temperature range is slightly lower than what humans expect, but it keeps cats comfortable and prevents them from overheating or dehydrating.

However, it is essential to note that cats’ temperature preferences may vary depending on their age, health, and coat thickness.

Monitor your cat’s behavior and physical indications of discomfort, such as panting or excessive grooming, and adjust the indoor temperature as necessary.

2. How outside temperature is too hot for cats


Cats can easily overheat when exposed to scorching weather. So what temperature do cats overheat? Although cats are okay in 90-degree weather, they are in danger of heat stroke if outdoor temperatures exceed 100° Fahrenheit (38° Celsius) and relative humidity levels are high.

Cats are usually safe in temperatures ranging from 45°F to 90°F (7°C to 32°C). They can tolerate the range of 80 degrees to 85 degrees Fahrenheit (27°C – 29°C). However, even within this temperature range, cats can be influenced by other variables such as humidity, wind, and direct sunlight.

If you get your cat to be outside, ensure your cat has access to shaded places and plenty of fresh water to avoid heat stroke or dehydration.

The Effect of High Temperature on a Cat’s Health


What heat can cats tolerate? Cats’ average body temperature is 100.5 to 102.5 degrees Fahrenheit (38.1°C and 39.2°C). However, the heat tolerance of cats is slightly lower, from 86 to 97 degrees Fahrenheit (30°C and 36°C). Temperatures above this range are especially too hot for kittens.

In other words, cats are more comfortable in cooler temperatures, and any significant deviation from this range can lead to various health issues.

You must be aware of what temperature is too hot for cats because high temps harm their health:

  • Dehydration: High temperatures can cause cats to lose fluids quickly, resulting in dehydration. This is dangerous and can lead to other health issues.
  • Heat stroke: Heat stroke happens when a cat’s body temperature rises to a dangerous level. This can harm the cat’s organs and, in extreme instances, be fatal.
  • Respiratory problems: High temperatures can cause excessive panting in cats, which can lead to respiratory problems. This is especially dangerous for cats who already have respiratory issues.
  • Skin problems: High temperatures can cause skin irritations and rashes in cats, especially in areas with less fur.
  • Behavioral changes: High temperatures can cause cats to become drowsy or lose their appetite.

Warning Signs of Overheating in Cats


Overheating, also known as hyperthermia, can harm a cat’s health. Here are some warning signs of cat overheating:

  • Heavy panting: Excessive panting in your cat could indicate overheating. While cats do not pant like dogs, they may pant heavily if overheated.
  • Restlessness: If your cat is pacing or acting restless, it could be a sign of overheating. Your cat may also be looking for cooler places to lie down.
  • Bright red tongue and gums: Overheating can cause your cat’s tongue and gums to turn bright red. The tongue and gums of a cat should be pink.
  • Lethargy: Overheating can cause your cat to become unusually tired or unresponsive.
  • Vomiting or diarrhea: If your cat vomits or has diarrhea, this could be a sign of overheating. This is because excessive heat can cause dehydration, leading to digestive problems.

If you notice any of these symptoms, take your cat to a cool, well-ventilated area and moisten its head, neck, and back to cool it down and lower its temperature.

How to Cool Down Your Cat in Hot Weather?


In summer, cats are prone to heat stroke and overheating, so taking precautions is critical to keep them cool. Here are some ways to keep your cat cool in hot weather:

  • Provide plenty of water: Make sure your cat always has access to plenty of fresh water. Consider adding ice cubes to the water to keep it cool.
  • Create a cool environment: Keep your cat in a cool, shaded area with good airflow. You can keep the room cool by using a fan or air conditioning.
  • Wet towels or cool water: Put wet towels in the freezer for a few minutes, and then put them over your cat’s body to help them cool down. You can also use cool water to gently wet your cat’s fur to help bring down its body temperature.
  • Frozen treats: Consider giving your cat frozen treats, such as ice cubes or ice cream for cats. This can help them stay cool and provide something good to eat.
  • Provide a cooling mat: Cooling mats or pads absorb heat from your cat’s body and can be a great way to keep them cool.

Although cats handle hot weather well, you should be aware that overheating can seriously impact their health. If your cat exhibits any signs of distress, act quickly to help it calm down and get medical assistance if required.

Hot Weather Safety Tips for Cats


Here are some hot weather safety recommendations for cats to keep them protected and healthy during extreme heat:

  • Add a few ice cubes to the water basin to keep it chilly.
  • Keep your home’s unscreened windows and doors closed, and ensure the adjustable screens are securely fastened.
  • Provide fresh running water to encourage drinking, not motionless water.
  • Don’t take the kitten with you in the car.
  • Close the curtains to keep the house cool.
  • Use a moist cloth to groom your cat.
  • Grooming cats more frequently than normal can stop issues brought on by extreme heat.


In conclusion, it’s important to know how hot is too hot for cats so you can watch out for their health when the weather is hot.

Although cats handle heat better than humans, they can easily get too hot, so it is essential to keep them in a cool, comfortable place to help them keep their body temperature stable. It’s better to err on the side of caution and take proactive measures to keep your feline friend safe and comfortable during hot weather.
