So I got a new rabbit a little over a week ago, I’ve done many bonding sessions with him and my previous bunny Penny, everything goes great when they are in a small space, I use a laundry basket. He has a pen set up that he goes into during the day (sleeps in his crate beside Penny in her crate), and he is allowed out into the house in short spurts when I have the other bunny put away, just so he can explore and get used to our home. He is becoming more and more territorial over his “area” each day, thumps and growls even when Penny just comes over to sniff, he wasn’t like this before. He is neutered and she is spayed, they fight terribly if they are put somewhere other than the laundry basket, I knew it was going to take a while, but he seems to get more unhappy here each day, does anyone have any advice? Thanks guys!
