I just got a second level of the rat rack from Freedom Breeder. I have two questions.

First.. what model are the tubs that are used in there? One of the tubs has a crack in it from me dropping it. I'd like to just go to the container store and buy a new tub, instead of paying the $11+ shipping for one from Freedom breeder. It looks like a commercial model.. like maybe Iris.. just wondered if anyone knew what it was.

Second.. I got the food funnel for easy filling of food hoppers.. the problem is, I don't know how it fits on there! They didn't send instructions, and they never answer my questions when I send them e-mail.. thought maybe I'd have better luck asking you guys.

Thanks.
