It is just a suction cup really - with a teaser toy attached. I got it at our base exchange but have seen them at WalMart and PetsMart Hartz makes the one I bought. Called it a Gone Fishin' toy. Not a magnet.
Thanks! I'm going to look for one of those. I have a Petco near work, so I'll stop by there tomorrow, maybe they have it. I think Elvis and JD would FLIP if I got them one of those!
