Figure 5.

Soiled cages after 2 wk of housing mice. These representative images of (A) shaved aspen, (B) corncob, (C) pelleted cellulose, and (D) refined diced cellulose were obtained at day 14 after cage change from above (left panel) and below (right panel) each cage. Cages showed visually similar accumulation of fecal material. Aspen and corncob cages show urine spots when viewed from the bottom of the cage, but cellulose products did not. Pelleted cellulose showed primarily fecal accumulation, whereas diced cellulose showed fecal accumulation and yellow discoloration.
