Cat Pulling Hair Out Of Tail. (see picture, which is of her drastically shedded tail). I just included this in a previous answer to someone’s question about a cat that would not raise its tail.
It also seems that this hair is not shedding but possibly being digested. Typically, hair is removed from the underside of the abdomen, the groin area, and the upper side of the cat in front of the tail area. I was working as a vet tech and brought him in to rule out any medical.
I´m turning to you for some advice.
