They'll be choosing each other. My only criterion was that she can't be bigger than he is or she won't be able to manage the corner in the Runaround setup. Other than that, just as long as they like each other, I don't care!
Well unfortunately things did not work out with the problem bunny, resulting in Tully getting a bitten and her having to back to the rescue
But he has just been back to meet another potential friend and it's looking good! They were at the rescue together since Tuesday with nothing more than a foot-stomp between them. I've just brought them back to Tully's (neutralised) hutch and they are snuggled in the litter tray together. Fingers crossed for a peaceful night. Photos tomorrow all being well!
