There are so many different variations on bedding, most of us try out a few until we find something that fits our lifestyle and pocket.
I'm not a fleece user, I tried it and didn't like all the washing but then I do have well over 40 pigs to accommodate. The fleece (once it is washed 3 times without fabric conditioner) allows the urine to wick through to the absorbent material used underneath - this can be newspaper, towels, inco pads, puppy training pads, etc. A quick sweep up/hoover up of the poo keeps it looking clean and the pigs do really like fleece to lay out on .
I use puppy training pads with deep litter hay, topped up every other day and cleaned out once a week, the pigs love it and the volume of waste is low as the 'uneaten hay' (council won't take animal bedding) goes in the garden recycling and the pads fold up nice and small for the bin.
For the poorly pigs I deal with I use puppy pads under vetbed, again the urine wicks straight through and the pigs stay very dry and very comfy. Vet bed goes in the wash and the pads in the bin once a week.
