Wow, it seems like most people flat missed the point of the OP's question. A post earlier (by a few weeks) either here on MR or on KindleBoards talked about her/his K3 separating at the bevel and screen. The K3 apparently has a glued down bevel to seal around the eInk screen. The glue doesn't hold well in some cases and appears to remain sticky around the edge of the bezel in some cases and the result is small objects like hair can get lodged between the bevel and the eInk screen. The OP was NOT talking about things sitting on top of the eInk screen but wedged in between it and the bevel. We have two cats and yes it is an occasional problem with cat hair (and other small airborne objects) getting wedged in the seam between the bevel and eInk. It is sometimes very difficult to get them to dislodge.

As far as cat and pet haters go, to each their own. But I personally find my cats to be much better company than most of the people I know, including most of my family.
