Hello. I have a 1.5 year old fixed mini rex named Helix. I have started noticing over this past month that my rabbit will run in circles around me. He gets free roam time for hours each day and He typically stays in a large carpeted room. I have started noticing, that if I leave the room to do school work and then come back in the room, my bunny will sprint over to me the moment I enter the room, and run in circles around me making a low grunting sound for about 5ish minutes. Then he will do bunny 500's and lots of binkying. After that, he runs around me a few more times and lays down to relax. Is this behavior normal for a bunny to circle you? I just want to make sure he's not stressed. Thanks!
