My sister smokes out in the backyard very often. At first Ruby seemed very intrested in those butts but then she really forgot about them or so I have seen. I hope so also. Although I have already worned my sister that she better pick these up because they can be harmful to our furbabies. I have said if they get to one because she is reluctant to pick them up I will be very angry. I said " Pick your butts up or I wil kick your butt".
