Cat reacts strangely to high-pitched sound produced by a comb in Henan, China

On November 5, 2026, in Henan, China, @Hǎoduōmī shared a funny video showing a cat reacting unexpectedly to the sound of a comb. In the video, a cat lies on a bed while someone repeatedly runs their fingers across the teeth of a comb, producing a high-pitched sound. Initially, the cat shows little reaction, but after the sound is repeated, it suddenly gets up and opens its mouth, appearing to gag. The reaction may be linked to cats' sensitivity to certain high-frequency sounds. According to veterinary information, some cats with Feline Audiogenic Reflex Seizures (FARS), also known as Tom and Jerry syndrome, can experience involuntary neurological responses to specific sounds. However, a gagging-like reaction alone is not enough to establish that a cat has this condition. Cats have sensitive hearing, and deliberately producing potentially distressing sounds to provoke a reaction should be avoided.
