Yes I am quite aware of that spot and so is my bf! He loves scratching near Twinkie's tail and he starts yelping and won't move like he is frozen in the spot he is in.Heather102180 said:Not sure if anyone knows this but cats have a very sensitive place on their backs, right where their tail begins. If you pat that continuosly or scratch it, they starts licking whatever is in front of them very rapidly. Try it....see if your cats have it. Mine do!
