Usually my rabbit comes up from his pen and chills in the living room for most of the day. Last night he was thumping quite a few times, and we had no idea why… Nothing had changed in the environment except for the fact that my maid was over cleaning the house. This morning, he hasn’t been thumping but he’s been running around all over the place, he usually just chills in the living room and eats hay or plays with toys. Should I be concerned about this behavior? Exploring all areas of the house is very unlike him
