[Tiger's Mom]

Well, I knew you would ask that . . .and the trainer did talk about it but of course being that I am so forgetful , now cannot remember. Anyway, there are more of the other kind on the market . . . and it has a stopper so you can only go so much which is a good thing. It is also the same one that my VET uses.

Perhaps someone might help me out and answer this question. . .
