I've been home the last week. I wake up, let my bunny out of her x-pen and she stays out until I go bed. I've been studying, so it's just me and her all day, so I am always observing her behavior... During the day, she is completely inactive. Like loafs all day long in the same spot. Gets up, yawns, stretches, eats drinks poops and then loafs. At first I thought she was depressed, bored, needs a bun friend. Then I've been staying up late and watching her behavior completely change. As soon as it's like midnight it's like a switch goes off. She's doing sprints from corner to corner. She runs and kicks her legs, binkies, flops. It's really weird. Today she has been sitting in the same place loafing for like 5hrs straight. Is this normal? I feel like she doesn't get enough exercise bc when I go to bed I have to put her back in her pen at her peak energy level.
