I'm all for letting your bunny sleep in your bed with you, but only if they decide that they are going to.
I took Helena into my room once because it has carpet (the area where her pen is has a tarp, but it is in the the hardwood floor living room) and let her chill in there for the evening with me. I got in bed and she promptly got up to join me. Granted, it was annoying the first few nights--she would come inspect me at 1am, burrow under my stuffed animals at 3am, and sit on my face at 5 am (because she was hungry?).
After about a week or two, she just gets in at bedtime, whether I'm in bed or not. She will escape from her pen at night if she is in there still (sometimes I get trapped in the library--thesis research
) and plop herself on "her spot," which is at the edge of my bed near my feet. I'll come home at 2am, turn on the lights in my room, and she is just sitting in her spot and glaring at me for waking her. She doesn't annoy me at night anymore, which actually makes me a little sad, but I appreciate the sleep.
She was peeing on her spot for a while (not much, just a few "this is mine" dribbles), so I washed my sheets (it came out really easily btw) and put one of the towels that I use to cover her cage on her spot and the marking stopped.
I definitely move in my sleep, but I think she just jumps down when I start invading her space. Maybe my bunny is just a light sleeper...
