EVERY night i pick up all the poop, hay & shavings that are on the fleece covered floor.
in some cages i change the litter (those that pee a lot), some i just add a small handful to top off. if they pee on the shelves or tile i wipe it down. i then give them fresh food and hay and wood and fix thier cage. Nine chins in eight cages and one handfed chin takes about 1 hour........that is with one or two coming out.
about 2 times per week i take everything out, wipe down the pans, get fresh fleece and shavings in all cages. i would like to do this 3 times a week, but honestly i have to take them all out to do it, so last night it took me almost 3 hours! of course i weighed them all and played a bit but it does take me a while.
oh and i sweep at least twice a day, every day!
