I have 5 colubrids of various species housed in AP cages 4'x1.5'(?) and use about 3in of aspen per cage. Anybody ever use a larger shop vac for cage cleaning? Currently I hand scoop as much as I can, vacuum, sanitize, then add fresh aspen. My little 1.5 gallon is way to small since I can almost fill a garbage bag 3/4 full after doing 5 cages. At work we have a shop vac mounted on top of a 55gal drum. Neat idea. Another consideration is dust. Not cool having aspen, feces and urine dust blown all over.
