You're worried about why your cat's ears are warm. Read this article to get the most accurate answer.

While petting the cat, you often feel the cat's ears are warm. This might make you think, "My cat's ears are warm, does my cat have a fever?"

So, in this article, we'll give you a detailed answer on why cats' ears are warm and how to identify the signs of illness in cats.

Why Are Cats' Ears Warm?

The ear of a cat is an organ that aids in controlling the cat's body temperature. Therefore, there is no need to be concerned if the cat's ears are warm whenever you touch and feel them.

Cat’s ears are usually warm because cats are warm-blooded animals that use a method to adjust their body temperature based on their surroundings. Although cats can release heat through their noses, cats' ears are pretty thin and lack fatty tissue or hair. As a result of their proximity to the environment, cats will frequently release heat through their ears, making them warm at all times.

What Is A Cat's Average Body Temperature?

The average body temperature of a healthy cat is 100 to 102 degrees Fahrenheit (38 to 39 degrees Celsius), which is higher than a human. Because cats' ears are one of cat heat-producing organs, they usually are warm to the touch.

Therefore, to determine if a cat has a fever, his body temperature must rise above 103.5 degrees Fahrenheit (39.7 degrees Celsius) within a few days. To correctly measure your cat's body temperature, the best method is to use a thermometer.

What Does A Warmer-Than-Normal Cat's Ears Indicate?

"Are cat’s ears supposed to be warm in regular conditions?" The answer is yes. However, if your cat's ears are warmer than usual, it could be a sign of an illness or possibly a physiological response to the environment. So, in that case, you need to use a thermometer to check your cat's temperature to confirm if he's sick or not.

If your cat's ears are noticeably warm and gradually warm up, it could be due to some common reasons such as:

Fever

Fever is also a common illness in cats. Cat fever can be caused by pyrogens found in bacteria, fungi, or viruses. Besides, some diseases and immune reactions to drugs can also cause your cat to become ill.

When the cat has a fever, his body temperature will rise and make his ears warmer than usual. In addition, each cat will also show different symptoms, such as dehydration, panting, rapid heartbeat, and coma.

Allergy

Allergies cause dilatation in the blood vessels surrounding the ear in cats, causing the ear temperature to rise. This type of illness usually occurs when cats ingest foods containing allergens, pollen, or insect bites.

When allergic, the cat's ears are red and warm. Besides, cats will also have itchy ears, so pay attention if he frequently scratches his head with his paws or rubs against the rough carpet.

Infection

In addition to bacterial and fungal infections, some diseases, such as feline ear mites, may specifically attack a cat's ears, raising the temperature of his ears.

These mites will enter the cat's ears and eat the thin inner skin, causing severe inflammation. If your cat has ear mites, see your veterinarian right away for a thorough examination and treatment.

Hyperthyroidism

The cat's body has several hormones that contribute to his increased body temperature, the most frequent is a thyroid hormone.

When a cat has tumors, his body produces many thyroid hormones, known as hyperthyroidism. This is a severe disease that can result in cardiac failure in cats.

Environment temperature

The temperature of the cat's ears is deeply affected by the ambient temperature. Especially on hot summer days can cause cat ears to become hot.

In this case, if your cat can cool down, there is no need to be worried. However, if he is unable to cool down on his own, he may develop heatstroke, leading to a stroke.

Panting and drooling, elevated heart rate, unconsciousness, and convulsions with diarrhea and vomiting are typical stroke symptoms in cats.

Feeling

The cat's temperature can fluctuate due to his emotional and physiological changes. However, this is no cause for concern because a cat's ears can get warm if he gets too excited, nervous, or angry, and once those feelings go away, his ears will return to an average temperature.

What Should You Do When A Cat's Ears Heat Up?

"Why are my cat's ears warm?" is a question that cat parents should not be worried about. But, if his ears become too hot, it might lead to significant problems.

So, for the safety of your cat's health, if you feel his ears are warmer than usual, it's best to use a thermometer to measure his body temperature accurately. In addition, it would help to inspect other sections of the cat's body, such as the belly, where the hair and skin are thin.

The high temperature in your home can also cause your cat's ears to get hotter. Therefore, cool down your cat by opening a window or using a fan or air conditioner. The ideal temperature for cats will be between 70 and 77 degrees F (20 to 25 degrees C). Besides, rehydrating the cat on hot days will also help his body become more comfortable.

However, if your cat has a hot ear accompanied by signs of a severe illness, seek the assistance of your veterinarian as soon as possible so they can diagnose and treat your cat.

What Does An Ear Hematoma Look Like in A Cat?

When a hematoma occurs in a cat's ear, it often looks like a blister. The flap of the cat's ear will feel warm, hot, and maybe tender to the touch.

Although there are many causes of a hematoma in a cat's ear, the most common cause, according to veterinarians, is ear mites. As a result, you should clean your cat's ears more frequently to avoid this issue.
