The optical microscopy pictures look like textile fibers. They don't look significantly different from the stuff I've tracked down and chased from any number of cleanrooms.

As to the the SEM images, not enough experience in that area to do more than speculate. I would expect synthetic fibers to have a uniform cross section, these don't. I see bulges and interrupted grooves. I don't see the scales or microfeatures I'd expect in fur or hair. Possibly vegetable origin?
