Some sounds can not only make your pet angry, but also cause long-term problems with the nervous system.
Cats' hearing is many times more sensitive than human hearing. There are nine sounds that seem normal to humans, but are too harsh for pets.
Household appliances
One of the main personal enemies of a cat is a vacuum cleaner. It makes the pet nervous and look for a place to hide. You can also include a blender and a washing machine in the list.

Child's cry
A baby's screaming or crying can cause physical pain to cats, not just anxiety.
Rustling foil
The effect on a cat is about the same as the sound of fingernails scraping on a blackboard has on people.
Dog barking
At the very least, it will make your pet tense up and analyze the situation to make sure that his health is not threatened by any aggressive dog.
Loud knock
The same situation as with household appliances. The noise of a drill, the sound of a hammer and other similar repair sounds can cause stress in an animal.
Firework
Fireworks scare pets just as much as thunder or the howl of a strong wind.
Doorbell
Hearing this sound, the cat immediately wakes up. Here it is not the sound itself that is annoying, but the expected arrival of strangers.
Many cats don't care, but there are some pets that are quicker to run and hide.
Cotton
A balloon explosion can take you by surprise, not just a human. Cats with their hearing have an even harder time with it.
Loud music
A real torture for a tailed friend. Cats especially can't stand music with heavy bass and rough vibrations.
