I honestly can’t quite remember. We used to mainly use the plastic CB-6000 cage which is great for exploring this for reasons I go into here, but that needs a rinse most days to keep things fresh.
We haven’t done a long long stint since getting a good metal cage – which is far easier to keep clean in. I think we did a week. But I just love taking him out and teasing and edging him too much. I do fancy the idea of doing longer and will do at some point just for interest, but on the whole it’s not very long pure lock ups for us.
