The mini rex girl seems very sweet and, for lack of a better word, gentle. Definitely not shy - she's one of the first to the cage bars to ask for scritches - more .... ladylike & refined, perhaps? She clearly wants love and attention, but she's polite about asking for it (unlike, say, Cassidy or Copperfield, who have no manners whatsoever when it comes to demanding attention from their human slaves!) She was very bonded to the Hotot-mix she arrived with who has subsequently been adopted, so clearly she likes the companionship of other buns. I hated seeing them split up, but under the circumstances, was grateful at least the Hotot-ish found a home.
As for bonding the black rabbit to other buns, that I have no idea about. As far as I know he has always been an only rabbit. I haven't seen any signs of aggression toward the other intact males he's been caged next to, if that counts for anything. Size-wise, he's a nice match for Katie Poofy Underpants (maybe a shade bigger, but not by a lot), and would require a lot less grooming! :biggrin2:
