isn't that odd?
in my years of browsing hardware, I'd swear I've seen such a thing. But to tell you where? Can't.

Great idea, though. :)
Sorry I'm not much help.

someone posted a picture of a kitchen with a dog feeding station. I think I remember seeing those kind of pulls.

Thanks for all the suggestions.

I'd love a metal one like the wooden one posted by ucgal. If I can't find that I think one of the ones Poohpup posted would probably be my 2nd choice if they come in different finishes. The cutouts would work for the upper drawers, but below I'll have large trash bin pullout type drawers for dog food containers and I'd rather not put a cutout into a space for food! That might be too tempting to the doggies!
