My rabbit Bonnie Jumps up gets all excited then runs off and repeats. She also greats us in the morning honking loudly and all excited when she's letting us know she needs feeding like a puppy. She also makes this noise whilst she eats her favourite treats. She is NOT angry or distressed (a few comments have been made regarding this) as you can see she willingly runs to me and is free to run away if she chooses.
