Einstein, how lucky you are. Our Sprawl-Mart doesn't have that it in its section, nor does it have any of the PetHead products (which I have seen in other Sprawl-Mart stores). Our little section is sad in my hometown.
You can find the Dremel for pets on Amazon for about $24. I would be terrified of grinding too much, although I'm terrified of cutting into the quick! I just nervous about it -- period.
