|Pinni in her all-fleece cage|
I've tried an all-fleeced cage a few times in the past. I first attempted it with my store-bought cage, and the results were laughable - it was wet and stinky within a day or two. I never tried that again. I continued to use shavings when I converted to the C&C cage, although I have fleeced the upper levels for years (and have been using a mix on the lower level for a year or so). Fleece is also my bedding of choice when traveling; it is much easier to pack than traditional shavings and combined with the grids, makes for a very quick and clean setup.
Pinni has a cobbled together fleece setup, as you can see from the photo. I don't have any fabric cut to size for the entire first level of the cage. Lucky for me, Pinni is not a burrower, because there are plenty of edges for her to get under. The fleece is less messy than my half-shaving setup, although Pinni manages to drag the hay all over the first floor when she has a mind to. I have to regularly remove the poo, instead of just sweeping it to the shavings-side of the cage. But overall, it has worked well. I suspect that the current setup is not large enough to accommodate two sows - I will either need to expand the cage or return to my half-and-half mix as I had before when I find Pinni a friend.
