Hi, yes I use fleece. I watched youtube videos by “squeak dreams” - a lady who has lots of videos on there. I stole a few of her hints and it worked for me. I put towels down for the absorbent layer and then fleece on top. You need to wash the fleece 3 times without fabric condition so that it wicks moisture down to the “absorbent layer”. It then keeps the piggies feet dry.
Yes they wee in it, but I use pee-pads on top of the fleece - under hidies and in corners they tend to wee and poo. I change them out every 1-2 days and sweep the whole cage out daily.
I also use an under bed storage box with a hole cut out as a “hay room”. Because they eat in there (and often sleep in there too) - they do most of their wee and poo in there. I top the hay up in the morning and change it all for fresh in the evening. I line the box with newspapers so it’s easy just to fold up the newspaper and hay and put it in the bin. Quick pet friendly squirt and wipe. New paper and hay - and bingo.
It sounds a lot but I’ve got a routine and it takes like 10 minutes. I have a fleece canopy over their “hay room” so they feel secure in there. I also have a pad at the “door” of the room - so the over spilled hay can be picked up and swept back into the box easily. I don’t get much hay in the rest of the cage.
I do a full cage clean about every 1-2 weeks because the daily clean usually keeps the smells down. I use a pet laundry bag to wash their stuff so no bits get stuck in my washer.
