I've had my ferret for about 2 weeks and she is about 7 weeks old. I read on the FML one day that they love t-shirts or blankets in their cage instead of wood shavings. At first she adored them! She would roll them around and sleep in them, but now that I've taken them out to wash, I've found about a 5x5 sq inch section missing. Over about a week she has had the blanket in her cage and has been acting fine. I know that cotton fibers are indigestible (undigestible?) but her poop looks like it always has, so she must be chewing the material into very fine pieces. She loves those blankets more than anything, but eating them can't be good for her. I'm sure I could find other things for her to roll up in or chew on. Please tell me if there is a serious problem or if this is acceptable. Daniel Dupriest [Posted in FML issue 2178]
