Normally I'd offer to help SJ but I just can't at the moment - I'm happy to lend out my hutch that is at Hettys if it helps anyone (but even that would have to wait until Hetty is back from hols I guess!)
chelle - I'm always up for helping a bunny in need if I can but to be perfectly honest, if you're in a situation where you have a pair of unspayed females, I would not foster another rabbit at the moment - it's just asking for a fight between your two. They have very acute sense of smell and if they smell another rabbit around (even if you think they are nowhere near each other) it is likely to send their hormones absolutely haywire and you could well end up with a serious fight. It can sometimes be bad enough with neutered rabbits but there's no way I'd risk it with unneutered ones, sorry
