Cassandra mastered going up and down stairs last night. It took Nadia several days to get the hang of them. I guess Cassandra's size helped. Cass even went back into her house on her own, going down the stairs and into her pen (not far from the bottom of the stairs). I'm going to see if she'll go up the stairs for play time on her own, too.
She was dancing all over and even flopping in bliss when she was out last night. She's such a joyful rabbit. Someone is going to get a great bun when they adopt her.
