Agreed! Homemade racks are the way to go IMO. There's also a good article on here for making tubs into rat enclosures if you don't have the tools laying around to build a rack (my current predicament lol):

I was trying to find the one that has the hardware cloth on the sides instead of the top (I think this is more efficient then having it on the top because of air flow and it allows you to stack the tubs) but I couldn't seem to find it. Oh well.
