OK. So I used to use bedding but my piggies (we have six) liked to kick it out of their cage and create a huge mess on the floor every day. Also, with 6 of them, it's really expensive to replace bedding once a week for three floors. So, I switched to fleece and we have a litter box on each floor. At first, they started pooping/peeing in their litter boxes (as well as everywhere else but I thought it was a good start.) The litter box is for ferrets and it fits into the corner of the cage and kind of loosely latches on the side. Anywho, now they just dump the entire thing over and use the bedding for underneath their pigloos. They have hammocks and little cozies and stuff to cuddle up in but they seem to like their bedding the best. They drag their hidy house over top of the emptied bedding to lay on it. Does this mean my piggies would rather have bedding than fleece? I've tried putting some material under their pigloo so it would be cozier in there but they continue to dump their litter box for bedding. The good news is that they tend to poop/pee the most in the corner where the litter box is, but they moved the litter box and used the tipped over unit for another hidey. They like redecorating. Maybe I should just switch back to bedding but geez is that costly. I use the carefresh in their litter boxes cause it doesn't take much to cover their litter boxes. Any thoughts?
