I too use AllBed, as my supplier (who, unless very much am mistaken, is the same as the OP's
) couldn't get hold of aubiose for me. I've been using it for a couple of months now.
Can leave 2 weeks (sometimes more) between substrate changes
Much easier to hoover up than card squares
Holds urine smell really well
Retains it's shape so the top stays dry.
My second bale smelled very strongly of citronella when i first opened it. it was fine after a couple of days in the cage though, and no rats showed any ill effects, so maybe i was being a bit sensitive that day!
Is a bit too 'spiky' for putting mums and litters on - so still need to store card bale too.
I would give it 8/10
