The other day I was sitting on my bed my rabbit happily bouncing and bounding around my room. All of a sudden, I realise he is no longer in my eye sight. I keep reading, figuring Fenton (my bun) is having a lay down under the bed (which he normally does) he’s been living soley in my room of the past 3 weeks, I keep the window open during the day (I live on a double storey house and the window opens over our indoor courtyard and not onto the street) so he’s very used to the noises and daily sounds that go about (he was previously an “outdoor rabbit” when owned by another lady).
All of a sudden I hear this banging, It’s Fenton under my bed, every 2 seconds banging his left foot on the ground. I instantly recognise this as “thumping” and look at his posture. He’s sitting, looking like the little fluff ball he is. 
I got very confused and wondered what was worrying him as I know it can be a way for him to communicate, I check outside my bedroom door to make sure my dog or cat are near by, I even listen. I do however, hear a small beeping from the washing machine down stairs and wonder if thats what is making him upset. 
Unsure, I crouch down and call for him, he sits still for a moment, and then stops thumping and slowly makes his way from out under the bed. I give him a little pet and cuddle to calm his nerves and he goes right back to binkying.
Later that night, my dad is lying on the floor of my room trying to “greet” Fenton. He’s very sweet trying to get Fenton to like him (as my rabbit seems to only enjoy bounding all over me). When all of a sudden a loud THUD!
He did a little thump and I though it might have been my dad so I ask him to leave.
I understand it could just be Fenton still going through adolescence and testing out his thumping abilities. I was just wondering because I’ve had him for almost a month now and this is the first time he has done it. And twice in one day!
