However, it’s important to understand how your cat’s respiratory system works and to take precautions when using a humidifier around pets. Are Humidifiers Good for Cats? the answer is, Both cold and warm mist humidifiers can be used for cats, but they have their advantages and disadvantages. This article examines the benefits and safety of humidifiers for cats, as well as the differences between hot and cold mist humidifiers.

What advantages could humidifiers provide for your cat?

 Cool mist humidifiers are safe for cats as they don't emit hot steam that can burn their sensitive skin or cause respiratory issues.

In humans, dry air can cause a dry cough and cause breathing difficulties, for example in cats. Let’s find out how a humidifier can help your cat.


Respiratory allergies, such as feline asthma, can cause your cat to cough regularly. Allergies can also cause your cat to breathe faster and more intensely. Asthma attacks in cats can be triggered by allergies, including pollen, dust mites, storage mites, and even household cleaning products.

Using a humidifier with clean, fragrance-free water can make the air less dry. This can help relieve your cat’s cough by moisturizing the airways. It might also help your cat breathe better.

Cat Flu

Symptoms of upper respiratory infections such as cat flu can be relieved by increasing humidity. Feline flu is caused by many viruses and bacteria, including feline herpes virus, calicivirus, and Bordatella.

Although vaccination can prevent upper respiratory tract infections, it is common for young kittens to become infected. Unfortunately, after a cat flu episode, a cat or kitten will often experience periodic symptoms throughout their lives, particularly during times of stress.

Cat flu symptoms include runny eyes and runny nose, and the volume of runny nose can make it difficult for your cat to breathe. Humidifiers and nebulizers can help clear mucus from your upper airways, making it easier to breathe.

Dry Skin

If your cat has dry or irritated skin, it may benefit from more humidity. However, if you’re concerned about your cat’s skin, ask your vet to investigate the cause before using a humidifier.

What Harms Can a Humidifier Cause to Your Cat?

So humidifiers sound like a great idea, right? But are there also disadvantages? Yes. There are many reasons why you should be very careful when using a humidifier around a cat or other pet. Here are some of the risks of using humidifiers around your furry friend:

Burns and Scalds

There are many types of humidifiers, including hot and cold mist humidifiers, ultrasonic humidifiers, and evaporative humidifiers. It is very important what type of humidifier you choose. Not all devices are safe for pets, as hot mist humidifiers use a heating system to bring water to a boil and create steam or mist.

Make sure that the humidifier used does not produce atomized boiling water. Otherwise, your curious cat could be drawn to the vibrations, get a little too close, and get a bad burn. Also, a cool mist humidifier or ultrasonic humidifier should be kept out of your cat’s reach to avoid accidents.


Increased humidity in the home can make breathing easier for both hairy and hairless residents. However, long-term high humidity can lead to moisture and mold problems. Mold spores in your home can cause irritation or infection of your cat’s respiratory tract, lungs, or other pets.

That’s why it’s best to monitor the humidity levels in your home and look carefully for signs of dampness, mold, or mildew. Also, clean all parts of the humidifier at the recommended intervals according to the manufacturer’s instructions.

Bacterial Growth

A warm, humid environment is not only an ideal breeding ground for mold; it is also a breeding ground for bacteria. This means that bacteria can multiply in the humidifier or diffuser and in the air in your home.

If you or your pets breathe in these bacteria, they can cause respiratory infections or pneumonia. For this reason, it is important to regularly clean and disinfect the humidifier using a manufacturer-approved pet-safe method.

Are Humidifiers Good for Cats?

Cool Mist humidifiers are safe for cats because they don’t emit a hot vapor that could burn their sensitive skin or cause breathing problems. Hot mist humidifiers, on the other hand, can be potentially dangerous for cats as they emit hot water vapor that can cause burns if spilled or if a curious cat gets too close.

 Cool mist humidifiers are safe for cats as they don't emit hot steam that can burn their sensitive skin or cause respiratory issues.

In addition, some humidifiers are scented or allow the use of essential oils. While these smells can be pleasant to humans, they can be harmful to cats. Cats have a very sensitive sense of smell and are easily overwhelmed by strong smells. Some essential oils, such as tea tree oil and eucalyptus oil, can be toxic to cats, causing symptoms such as vomiting, diarrhea, and difficulty breathing.

That’s why it’s important to be careful when using humidifiers around cats and to avoid using perfumes or essential oils that can harm them.

Hot and Cold Mist Humidifiers

hot and cold mist humidifiers can be beneficial for cats. Hot mist humidifiers, called steam vaporizers, heat water to create steam. This can help relieve congestion and relieve discomfort in the respiratory system. However, they pose a burn hazard to cats if they get too close or drop the device.

Cool mist humidifiers, including ultrasonic and evaporative humidifiers, emit a cool mist into the air. They can help maintain optimal humidity without the risk of burns, making them safer around pets. However, they can be a bit noisy, which could bother sensitive cats.

In both cases, the humidifier must be placed out of the cat’s reach to avoid accidents and must not be used with additives such as essential oils that can harm cats. Proper cleaning and maintenance of the humidifier is also important to prevent the growth of bacteria or mold.
