Body language can help you unravel the mysteries of your domestic cat.
The position of the tail will help with this, as it will indicate the mood, feelings and emotions of the furry creature.
Communication
The tail is a means of communication for a cat. The position of the tail will tell you what mood the fluffy one is in, what feelings and emotions she is experiencing at the moment.

Smells
Cats perceive the world through smells. Therefore, with the help of pheromones in the scent glands on the tail, they read information about surrounding objects and people.
Control
Cats jump and run dexterously thanks to their tail. This organ serves them as a ballast to maintain balance.
Pipe
Not every animal can hold its tail up. Domestic cats are able to hold their tails upright when walking.
Wild cats cannot do this: they hold their tails either horizontally or between their legs.
Spine
In cats, the spine forms the basis of the skeleton and extends beyond the sacrum to form the tail.
