Read the thread on the woofing cat and it made me smile as we have a woofing rabbit. She only does it when she's cross with us (won't let her escape to the cellar or sit on the sofa) but it sounds like a small angry dog. She also does a chirping sound when she's happy and regularly does a weird kind of gurgling noise which I haven't worked out yet.
I've had a few rabbits in the past and I've never had one so vocal. She also likes to roll over and lie on her back with her legs in the air.
Anyone else have a weird bunny?
