Is Humidity Bad for Cats

Cats have different reactions to different humidity levels.

It depends on the season.  

Keep reading and I'll break it down!

Your Cat vs High humidity 

It's true that cats have more endurance than us and aren't bothered by high temperatures. 

But there are levels of heat that even your noble cat must bend the knee to…

Temperatures greater than 90°F.

The consequences of high humidity are heat stroke, heat exhaustion and dehydration.

It's hard to spot whether your cat is about to have heat stroke compared to other animals.

Watch out for these signs:

  • Excessive Panting
  • Drooling
  • Bright Red Tongue
  • Dizziness
  • Weakness

QUICK TIP: Your cat always give hints of the discomfort. One example is if they look for a shady area.

What about low humidity levels?

Low humidity has to be better for your cat, right?


It's better but it comes with its own set of problems.

  • Dry coat filled with dandruff
  • Non-Stop scratching
  • Coughing
  • Sneezing

It's definitely not close to as bad as high humidity. Just more uncomfortable for your cat.

Can Cats Be Around Humidifiers?

Do Ultrasonic Humidifiers Bother Cats?



Because they can’t hear them. Cats have better hearing than humans and they still can’t hear this humidifier.

Ultrasonic Humidifiers operate at 20 TIMES the frequency that cats can hear.

Some cat owners say that their cats suddenly turn into Inspector Gadget… 

Can they actually hear the sound? 

I know…

that's supposed to be impossible! Do you have a super cat on your hands?

The explanation's simple. (Not that I am against super cats)

Your cats won’t not hear the humidifier working. But it will hear the small fan motor spinning in the humidifier.

The sound of the motor changes as it travels through water. 

In this case curiosity won't kill the cat!
