BEST MINI LOP RABBIT CAGE FLOORING? NOT SAWDUST :)? - vinyl dog bed

I have a niche for my Mini Lop and gettin him Saturday
Tray in the cage is made of metal, does not believe in plastic GNA quite loud, and I do not really like the use of sawdust as JS is a mess, as the tray is not deep enough for EHV I marveled over the carpet or carpet, vinyl or what? What to do with, I thought half of the cage on the bed, carpets, etc., and the lower part of the sand bed, etc., with vinyl flooring do what you like best?
Thank you:)
