Many people believe that cats often wash because of their cleanliness. Yes, it is. However, this is not the single reason. It is also in this way when the animal licks the necessary amount of substance from the coat, which contains vitamin B. It is needed in order to regulate the mental balance of the cat. If not to allow the animal to perform this “ritual” for a long period, it will become very aggressive and may even die of stress. With the help of wool licking, animals regulate an optimal body temperature. Quadrupeds have a space, filled with air between the skin and fur. Their tongue can change its thickness and thus cool its body in heat or warm it at a low temperature.
