so. y'know. i have rats. and i have to clean their cage. the easiest way for me to do this (as of yet) is to move them all to either the bottom level or top three levels

_______/__________ what the levels of said cage look like for reference)
So i move my rats to the bottom layer, and remove the ramp leading to the second.
and then CHRIS. climbs up the bars to the second layer. okay, i thought. he's done this before, i just need to remove the ramp leading to the third level. so i do.
he climbs up to the third level. (i feel i should mention that the 3rd level is a full sheet of plastic with a hole for goin down)
i eventually solve the problem by putting their house in the hole so they can't get up.
