Well Im no expert beleive me, but my girl does that occasionally too. Its almost for her like a little tantrum.."your going to put me in here when I dont want to? well here you go" I came home yesterday after being gone 1.5 hours and she had basically thrown the poop around the cage...today it was on her bed in a nice smooshed pile...now she will go for four-5 days and be an angel.its a pattern,.then day 6 "to heck with it" is her motto..
