Cat owner captures “the wave” on video – why does the fur twitch when stroked?. The trunk skin muscle, which is completely called “Musculus cutaneus trunci”, is responsible for the twitching.

The reflex helps animals to defend themselves against insects and is also known as the panniculus reflex. If the reflex is reduced or absent, the cat may be stressed, agitated or anxious. Other mammals such as dogs and horses also have the trunk skin Muscle.
