Daysi, this is not a wierd question - in fact, it's a very good one. I breed ferrets and found this to be a chronic problem. Occasionally, a piece of clay litter would stick on a butt and get sucked up inside. Oh, how those babies screamed. So now I use Pine Fresh Pellets - recycled newspaper pellets are ok also. I don't recommend using clay litter for ferrets until they are about 12 weeks old. I have a litter that is almost 5 weeks old now, they've just started eating baby food and Marshalls Premium Ferret Diet, and although their eyes aren't open yet, they have started using the litter pan already. I have had no problems with any of the pieces getting stuck on butts, and none of them has had any problems with prolapsed rectums either - which clay litter can sometimes cause as well - the babies strain trying to get the clay off and out, causing the rectum to prolapse. My recommendation for not using clay litter until 12 wks is just that - my own personal recommendation - others may use clay and not have a problem, but I prefer to take no chances.
