For several weeks now An An has been behaving weirdly. And loudly. She seems to be having some kind of obsessive compulsive disorder. Instead of entering her igloo through the door she would go to the back, lift it up with her snout and drag out her blanket. Then she will stuff it in her pouch and bring it into the igloo using the door. Then she will go out again, lift the back of the igloo with her snout, drag out her blanket and repeat the whole process endlessly. Since it looked like an exhausting disorder sometimes I turn her house upside down to stop the ruckus. The next morning I found her sleeping inside the toilet with her blanket.
