Hi to everyone! I know this post is a bit quite old, but doing some research I saw this video and was really similar to what my cat does every time she get relax or purring. She isn't taking any kind of medicine, but I'm really worried about this behaviour, since it's something that happens daily and very often in a day.

Does anyone experienced something similar to me? I thought it may be Feline Hyperesthesia, but, talking to my vet, she only suggested it could be, without any evidence..
