I think a larger cage may actually be easier to clean than a smaller one! High traffic (wee!) areas could be cleaned independently of the rest as and when needed. I found that when I increased my cages from 120 to 160 they were much easier to manage
I was thinking more from a point of view of would a large space scare them?
But it seems to be working out ok
To start with in the big cage they didn't seem to leave the huts but they are more now
