What’s The Ideal Temperature At Home For A Cat?

When I leave my cat alone at home or when I go to sleep at night and I see her sleeping in the living room I wonder what would be the ideal temperature for her, what it’s too hot for me maybe it’s great for her and viceversa. So I decided to investigate and find out.

What I learned is that the ideal temperature for a cat depends on several factors, breed, age, size, health and even the environment where the cat is used to. In general terms, cats tolerate more warm temperatures than most people considering their body temperature is from 100.5 to 102.5 degrees. There is not really a magic number because it will depend on your cat’s adaptability to the temperatures and this will depend on several factors. You need to analyze these factors to figure out if your cat will be fine with normal room temperature or if it will need some adjustments.



Breed: Long-haired cats tolerate better cool temperatures than short-haired cats. For example, the Siberian cat is much more prepared for cold temperatures than a Burmese due to its thick fur that warms up its body. Cats such as Siberian, Maine Coon or Norwegian Forest Cats even have their paws covered by hair designed to walk in the snow or cold forest. Cats with thick coats may feel more uncomfortable with higher temperatures than short-haired cats.

Age: Kittens need higher temperatures than adult cats. A kitten could even suffer hypothermia in normal environmental temperatures due to the lack of capacity to retain body heat. Also, old cats need more warm temperatures than young adult cats as they usually suffer bone or joint pain.

Size: The smaller your cat, the less capacity to retain body heat. Also, if your cat is slim with low body fat you need to provide more sources of heat for it to feel comfortable and safe. On the other hand, if your cat is overweight it’ll probably be able to handle cool temperatures a little better.

Health: Cats with thyroid problems could be more prone to avoid too much heat. If a cat is suffering an infection or another type of sickness you need to provide your pet a warmer environment than usual, with a heated pet bed or heated blanket.



During winter:

If you have a healthy long haired cat, big sized or fat cat you most likely won’t need to worry too much about your pet from being too cold if you keep your pet indoors. The same if you have a cat with a thyroid condition that makes it less tolerant to heat. Keep the temperature between 60 and 68 if you leave them alone. After choosing a temperature in this range you can adjust it later according to your cat’s behavior.  If your cat is rolling up too much try to set the temperature on the higher side. Every cat is more or less sensitive to cold temperatures, even long-haired cats.

On the other hand, if you have a skinny or short haired small cat you need to provide sources of heat in case your cat needs warmness to keep its body’s temperature during cold weather. If you can afford it, keep the temperature between 78 and 80. If you have a kitten, you need to set the temperature on a higher side and have a heated pet bed to keep it warm if needed.

During summer:

If you have a long-haired, big sized or overweight cat you may need to leave a temperature about 80 (or below) if your house gets too hot above that temperature. If you can’t afford to leave the air conditioner “on” you can get a cooling pet bed so your feline friend has the chance to cool down if it feels too hot.

If your cat is slim and small or short haired hot temperature won’t bother it too much. Consider a temperature between 85 to 90, but leaving a fan or a window opened, making sure the air circulates. A kitten will tolerate the 90s much better than an adult cat.



Cats have their ways to balance their body temperatures, either seeking heat from different sources at home or trying to reach cold areas to cool down. If your home doesn’t provide these elements for your cat to adapt, it will be most likely that your pet will be too hot or too cold at some point.

Cat and sunlight

When cats feel cold, they try to reach higher locations where the sun hits and heat rises. Does your house have high areas where the sun hits so your cat jump on and get warm in case it gets a little chilly? Cats like to seek warmness by staying in high places where they can enjoy the sunlight, next to a window. If your cat doesn’t have access to a window trying to get a window perch for your cat. They are easy to install and your cat will have the opportunity to chill, enjoying the sun heat without the need of a cat tree or other piece of furniture.

Also, if your house is fully tiled floored make sure to provide enough warm areas where your cat can rest, especially in winters, remember that cats don’t always like to sleep in the same place. Consider a heated pet bed as an option if you have a small, short-haired cat or a kitten.

Think like a cat and you will find ways to provide your pet the elements they need to adapt to the temperature, even if you set the recommended temperature at home when you leave them alone, it is always good to provide your cat extra help in case that temperature doesn’t make your pet feel comfortable.

In summary, together with considering your cat’s characteristics to set the room temperature, make sure your cat has a source of warmness in winter and a cool area in summer when leaving them alone.
