We discovered today that our pair of female buns are infact brother and sister.
They are 4 months old and very well handled by the kids, who have decided that they'd prefer to keep the quieter female.
Mr bunny is a black and white spotted lop, very cute and friendly, but also very lively so not really suitable as a pet for very young children.
For obvious reasons he has to go asap, so come on all you bunny lovers, someone please give him a home!
