Bunny is just over a year old and I have had her since she was 6 months old. She is a house bunny with free reign of my living room. She has never been a really cuddly bunny but happy to be stroked, sit on the sofa next to me etc.
Over the last 2 weeks she has started to misbehave when I am out of the room/house. It’s all safe for her but she has started jumping up on sides, knocking things off, chewing etc. She never did this before. I have started putting her in her cage overnight so she doesnt’t hurt herself. Over the last couple of days she has started nipping me. I never pick her up but she usually jumps on me sits on my lap and then off again onto the sofa. She has now started nipping my leg when on my lap or my ankles when she is on the floor and I am sat on the sofa.
Does anyone have any ideas why this might be? There are no changes to her set up (other than leaving her in her cage overnight, but she doesnt seem to mind that) and she has always been pretty content with the set up I have for her.

Any help or advice would be very much appreciated
