I am actually looking to switch away from fleece (or at least, "all fleece") at the moment. It worked "okay". It wicked well and held up long enough before a full change, etc. But I have to use a laundromat (don't own my own washer and dryer) and live in an apartment, and it has been time-consuming and expensive to wash them. They are really bulky with the U-Haul blankets and in a busy month the laundry piles up and starts smelling if you don't keep on top of it (which I can't always do). We also have to worry about landlords fussing about mess and can't shake out the U-Hauls and fleece to get bits of stuff off them in a condo community where they "keep up the grounds". I want to recycle my fleece liners and U-Hauls into smaller pieces and use them as soakers in the cuddle cups instead, and use an organic bedding like hay/proper sort of shavings/proper sort of clean wood pellets from the local animal feed store for most of the cage. So I think fleece is great - but a lot of your choices for housing and bedding are going to depend on your personal circumstances. One thing that helped me hugely was getting the cages up off a low level and up to a much higher level, on top of a big long banquet table. With a chronic illness and bad knees, bending over all the time to clean out the cages was just killing me. This way they are at waist-height and I don't have to bend over. I also switched back to Midwest cages because they seem to hold together better (jointed more stably) and they make specific covers to fit (though I hate the swinging little hinges on those covers that are always catching). So I have not found my perfect solution yet for cavy care by ALL means, but all-fleece and C&C cages have not really worked well for me, after trying them for quite a number of months now.
