So the bunnies are living in the house while we work on their hutch. I opened the crate door to let them out to play, since they're so sweet. Anyways, I just heard one squeal, not like... bunny distress.... but a repeated "EEeee, EEeeee, Eeee". I thought it had gotten a foot stuck or something. But no, it was fine! I walked up and it looked up at me on back feet like "what?". Hopped out of the cage front and greeted me even. I've never EVER heard a rabbit make a noise like... a Guinea pig squeal, ever. Is it normal? What does it mean? I checked it over real good.. thinking maybe it had gas pains from the change in pellet types... but... nothing wrong with it, acting perfectly fine, sweet, social, full of play and antics.
