I finally threw out the old pillow/blanket which stank like my hamsters, or worse. Didn't have time to sew them a new one until yesterday and no sooner had I placed it inside the cage, Mimi and Momokuai were tugging at it trying to claim ownership. My sister's hamsters (which actually used to be my hamsters) are more loyal to their possessions. Father Momo still keeps the one I sewed for him last year, the first pillow he owned. When Ping and Lele pissed on it my sister gave it a new case. She told me that Momo threw it out of his window. My sister went, "Ungrateful @#*!%# hamster".
