If a cat thumps its tail on the floor, it does not always mean that it is irritated.
We'll tell you how to determine a cat's mood by its tail.
If a cat is lying quietly and its tail is twitching slightly, it is probably watching something that has caught its attention.
If a cat has crouched down, raised its ears and is wagging the tip of its tail, its hunting instinct has most likely awakened.
If a lying cat wags its entire tail, it is giving a clear signal – do not approach.
This behavior may also indicate that your pet is experiencing severe discomfort or pain.
