Tigger used to hate it. Lulu loved it and you could hit her with her tail, she would let you hit her on the rump all day
Holly would go crazy purring and other noises she would get really excited. I was told by a vet once that the rump is very sensitive in female cats.
Zoonie likes it more than Astrophe, but both of them like being hit with their own tails.
Cats are weird
