Thanks all for the support and advice, and also for understanding my predicament. It's so hard to know what to do for the best isn't it.
Julia25, Alfie lives outside but I have two dogs, one of whom is very prey driven, so it wouldn't be an option..... which is a shame because I think Alfie would love being a house bunny.
I've been thinking long and hard about it all since we lost Lola and have been looking on rabbit rehome/local rescue sites just in case there happens to be somebunny that would sway my decision. However, tonight I fed Alfie and have noticed that he has an abscess on his face next to his ear (it was treated a few mths ago now but must have come back) - he's eating well for the moment so I've got him booked in at the vet tomorrow but, while he's ill himself, then bonding plans are on hold either way.
