Debbie wanted to know what carpet that my ferrets don't bother to dig in. It is the kind that is very flat maybe it could be used outdoors. I live in an rental apartment and it is one of those cheaper carpets. It does have a pad under it so it is not on hard surface. I would think any carpet that is more like a "weaved-into" type instead of plush prevent ferrets digging because a plush seems like something that they can get into deeper and think they can get to the center of the earth if they keep at it. Think about it, dip your fingers into the carpet, if it goes into past the surface, don't you think the ferrets might think they can get into it? I like this carpet because it is halfway between the cold hard floors and the soft plush. If they do an "accident" it is much easier to clean than plush. I do like hardwood floors, I haven't experenced using area or throw rugs with hardwood floors yet but would like to know how they fare compared to wall to wall carpeting. Hope this helps, John [Posted in FML issue 2464]
