Let’s look at the benefits of using a humidifier for your cats.

How Humidifiers Can Benefit Cats
Prevents respiratory issues
Dry air causes mucus in the nasal passages to dry out, leading to inflammation, sneezing, or dry coughing. This can lead to the formation of scabs and sores inside their noses.
A humidifier will moisten the air and help to keep the mucus soft and flowing.
Prevents dehydration
Humidity can promote better hydration and reduce the risk of dehydration. Especially important for cats who are prone to urinary tract problems.
Alleviates dry skin
Increased moisture in the air can help to alleviate dry skin. Cats with dry skin or dander will tend to scratch the itchy patches, often causing wounds that bleed and can become infected.
Enhances a healthy coat
Dry air will dry out a cat’s fur like it dries out our hair. Dry fur will become brittle and look dull. Hair can break off, leaving bald patches. Humidity helps keep a coat looking smooth, supple, and shiny.
Reduces the risk of infections
Dry air can be a breeding ground for various allergens, microorganisms, bacteria, and viruses, which can spread quickly and cause various health issues, such as runny noses, sneezing, allergies, red eyes, coughs, and breathing difficulties.
However, by maintaining optimal humidity levels and keeping the air moist, you can minimize the risk of infection and provide a safer living space for your beloved pets.
Reduces snoring
Cats can snore!
And, this is caused by several factors, from blockages in the nasal canal to tumors or foreign objects stuck in the airways.
Once you have consulted with your vet to rule out more severe causes, installing a humidifier is an excellent non-medical solution to keep the air moist and reduce snoring.

Potential Risks of Using a Humidifier for Cats?
Like most household appliances, care must be taken to make sure the safety of pets and people comes first. Here are some things to consider when installing a humidifier for your cat.
Over-humidification
If your humidity levels become too high, the air will be excessively moist, which leads to mold and bacterial growth. This can cause health issues for both cats and humans.
Many humidifiers can be set to maintain preset humidity levels, helping to reduce this risk. Condensation on windows, damp walls, and musty odors are signs of over-humidification.
Hot water or steam can be dangerous
Warm mist humidifiers use heated water and emit hot steam, which can be a safety hazard to your pet if knocked over or unattended. To learn more about different types of humidifiers, look at our article here.
Improper cleaning
Humidifiers must be cleaned regularly. Combining heat and water creates the perfect breeding ground for harmful bacteria. Mold, mildew, and minerals accumulate in the device and can be expelled into the air you breathe.
Regular cleaning will easily prevent this danger. Here is our comprehensive article on How To Clean Your Home Humidifier.
White dust
Using tap or hard water in a humidifier can lead to fine layers of white dust being expelled into the air. White dust accumulates on surfaces and can cause allergies and respiratory issues.
Using distilled water or boiled water will resolve the problem. If your cat is sensitive to dust, an evaporative humidifier may help to lessen the white dust.
Oil additives can be dangerous.
Adding essential oils or additives to your water may be great for humans but can be toxic to cats.
Curious Cats
Ultrasonic humidifiers emit a visible mist which some cats can become obsessed with. It is not ideal for humans or cats to inhale the mist directly from a humidifier.
If this type of thing distracts your kitten. In that case, an evaporative humidifier is a better option, as there is no mist that you can see.

Are cool mist humidifiers safe for cats?
