I read on a US forum that mattress protectors made good absorbent bedding under fleece so I decided to give it a try. They are awesome! Primark sells king size ones for £5 and cut in half they gave me two layers for my 2x4 C&C. They absorb really well, was so surprised. They are so much better than towels, the newsaper on the bottom wasn't even wet after a week! With towells it's normally quite soggy and they are a lot easier to lay out in the bottom of the cage f you have awkward bits under a 2nd floor. Just thought I'd share in case anyone was interested.
