Reply #56: I think there is something in the timing of how a mouse moves or how a tail

wags that is irrissistable to a cat. I once had a cat video that had little mice and little birds in it. Both my cats loved it and tried to get into the tv to catch the critters on the screen. Mice move a little then stop. Then they move again. So do birds. A tail wagging must remind them of their youth playing with their sisters and brothers.
