I have fleece for my rescue cages (6 double FNs), and the rest of my cages/runs are on shavings. While I like the fleece, I seem to be constantly washing it, vacuuming up poos, changing it out. With me having a rescue, there's people coming by all the time, so it doesn't only have to look clean for me, but it also has to look clean for the potential adopters. And fleece just doesn't look that clean, pretty quickly, in my book. Give it a day after you put in the liner and there's poo everywhere. If you have chins that pee and poo everywhere, and dig food out of their bowls, you have pellet-shavings everywhere and then on day 2, the fleece looks like you haven't washed it for months cause of the pellet shavings sticking to the wet fleece.
I have extra liners, so I can switch the liners a few times and then wash them all at once. But I refuse to put those grimy things in my own washing machine, so I end up going to the laundromat. Well, I pay a neighbor kid to take them and sit there for me, but that's beside the point. Then I'm paying more cause of what it costs to wash and dry them at the laundromat.
That said. I can't imagine the amount of shavings I'd need for that many large cages, and I will not be switching to shavings for those cages anytime soon. I use finely shredded paper, and I already have it throughout my house, when only using it for the runs, so I will not be adding 6 double-panned large cages to the list of shavings-using cages unless I want to cover my entire upper floor in shavings as well. Lol.
My personal opinion is that, the fleece is fine if you are anal-retentive and clean 24/7. But the shavings sort of hide the poos better, and at the end of the week, the shavings look a lot cleaner than a fleece liner that's never been vacuumed does. If the chin is potty trained, I suppose that makes it a heck of a lot easier. Mine just dump the bowls, and then I have more of a mess, and I have rescues anyway, so it's really not worth the effort. I will be sticking with the fleece for those cages, but I feel like it's really a monumental effort to keep the fleece looking good.
Plus, several chins have decided to chew holes through the top layer of fleece on some of the liners.
To each their own, but I'm not as happy with the fleece liners as I thought I would be.
