Gerbils are meant to be re-used, right? But they eventually die.
I think that puts 'em as durables.
Better break out the hand receipts.
Great, now what am I supposed to do with a govt-issued, durable, gerbil? I'm sure as hell not gonna use it, I can't sell it, can't even feed it to the cats. Dammit, just another mouth to feed...
