A cat's desire to hide is a very bad sign.
If a fluffy creature suddenly wanted to appear “invisible,” it means that it either felt vulnerable or was very scared of something.
Of course, a cat owner cannot ignore such a situation.
But you shouldn’t try to pull your four-legged friend out of the “shelter”.
Before taking action, the owner of a furry friend should analyze the possible reasons for the pet’s strange behavior.
There are several possible explanations:
The main rule is: "Don't make the situation worse."
Don't make noise, don't scold the cat, don't try to pull it out... In general, don't scare the animal even more.
Let your four-legged friend calm down on his own and stop hiding.
If you suspect that your cat was in "hiding" due to pain and not due to external factors, then take the animal to a veterinary clinic.
