Hi there! 
So I lived in a 2 bedroom apartment. 
My boyfriend and I share one room, my girls share the other room. 
BOTH rooms are carpeted and my room is not completely ferret proofed (broken vents that the landlord still won't fix, urg) so the girls have play time in their room and outside. Inside of their room, there is a closet. THEY TORE UP THE CARPET AROUND THE DOOR TO THE CLOSET! Every time they come out for play time they run over to the closet door and start digging away at the carpet! (Mostly Izzy, Iggy just follows her lead sometimes) I tried to keep the closet door open for them but once the closet is open it's like a dump zone (literally). So either the door is open and they poop EVERYWHERE (which is weird, they are VERY good with the litterbox, it's only in the closet that they go beserk), or I leave the door closed and they tear up the carpet. How do I stop this? I don't understand. My girls are very good listeners but this ONE thing they refuse to listen to me. Urg!
