At least once everyone has seen when a domestic and calm pet was scared of something.
But at that moment she would hunch her back, fluff up her tail and turn sideways to the danger in order to slowly retreat.
The cat looks aggressive, it seems that it is about to release its claws. At the same time, it can even hiss, bark in the direction that it considers dangerous.
In this case, the pet backs away, and is confused and may be frightened in certain directions.
The animal adopts this pose by chance.
A hump (a wheel-shaped back) in a cat is an indicator that it is very confused, scared, or threatened by something.
She fluffs up her fur only to appear bigger.
As experts note, such a pose is considered defensive, but possible attack. In case of rage, the pet will attack, but most often it will prefer to hide from sight.
