Why are my cat's ears warm?

The temperature of your cat's ears will naturally fluctuate, and while this can sometimes be harmless, at other times it can indicate an issue. Today, our Farmington Hills vets share some of the potential causes and symptoms behind your cat's warm ears and what steps you should take if you have concerns.

Why are my cat's ears hot?

While petting your cat, you may realize that their ears are warmer than usual. This can lead you to wonder 'are my cat's ears supposed to be warm?'

Well, cats can have warm ears for many different reasons, and some of them are perfectly normal. If you pet a cat with hot ears, some of the possible reasons may be:

  1. No reason at all
  2. Responding to the weather
  3. Allergies
  4. Fever
  5. Ear Mites
  6. Ear Infection

Here we go into more detail about each of these reasons and what you should do in these situations:

1. There Is No Reason

It is important to understand that a cat's normal body temperature is slightly higher than a human's. A cat's body temperature ranges from 101° to 102.5°, compared to humans who typically have a temperature of 98.6° or lower.

The takeaway here is that a cat's ears should feel just a bit warm. If your cat is acting normal otherwise, then there shouldn't be any need to worry.

2. Changes in Weather

It's not a coincidence that your cat's ears warm up as the temperature rises. It's just your cat regulating its internal temperature. To prevent overheating, blood flow increases to the ears, paws, and nose, allowing them to easily expel excess heat.

However, extreme heat is still very dangerous to cats. Make sure you are keeping your cat cool by brushing them daily, providing them with a shaded spot, and making sure they have plenty of water.

3. Allergies

Cats, like humans, can have allergies. These are some of the most common medical conditions in cats. Seasonal irritants such as pollen and grass, insects, and, in some cases, food can all cause allergic reactions.

Symptoms of allergies usually include sneezing, wheezing, watery eyes, excessive licking, and, you guessed it, hot ears. If you suspect your cat may have allergies, you should speak with your vet.

4. Fever

Moving on to more serious issues, a cat's warm ears could indicate a fever. However, warm ears will not be the only indicator. If your cat is ill, you will likely notice or feel a warm belly. Additional symptoms may include:

  • Isolating or not wanting to play
  • Change in appetite
  • Vomiting
  • Diarrhea
  • Lethargy

Contact your vet or nearest emergency veterinary clinic right away if your cat is showing any signs that they are experiencing a fever.

5. Ear Mites

Some cats can experience ear mite infestations. These contagious parasites live within the ear canal and reproduce continuously throughout their life.

Ear mites are a common problem for cats, causing severe itching and discomfort. They feed on the wax and oils in the ear canal, causing inflammation (hence the warm ears) and possible secondary infections.

Your cat will need to see a veterinarian for medication to help get rid of the mites. Without proper treatment, ear mites can spread to other pets in the household as well as to you. It is critical to see a veterinarian to accurately diagnose and treat the infestation, as over-the-counter remedies may be ineffective.

Routine preventive care offered at our veterinary clinic is an ideal method of preventing many different types of parasitic infections. Speak to us about scheduling a preventive care visit.

6. Ear Infections

Ear mites are among the most common causes of cat ear infections. However, they are not the only possible explanation. Other causes include dirty, overly waxy ears, food allergies, environmental allergies, and trauma, such as a scratch or object stuck in the ear. In addition to warm ears, you may observe:

  • A loss of balance
  • Itching & head shaking
  • A foul odor in the ear
  • Red, inflamed ears
  • Abundant ear wax
  • Rubbing ears on the floor or furniture

Ear infections can be painful for cats and can lead to hearing loss if ignored. This makes diagnosis and treatment a crucial step. Contact your vet right away if you notice any of the signs listed above.
