I am always worried about that too. Rucy used to love to get up on high places and jump around. I was okay with her jumping from chair to chair and to other pieces of furniture but there were some daredevil acts that I would not allow her to continue (like the time I caught her doing a tightrope act on the back of the couch) So funny how different Jack is – he is scared of high places!
I never saw her fall, but they are are also free roaming, and one day I noticed she was breathing funny, I raced her to the vet and it was finally determined that she has a hernia.
Now the vet said this could have been congenital, but it can also come from something hitting her hard, (like an accidental bunny bunt) or her falling and landing hard on her feet. Since there had been no accidental bunny bunt, then it’s either congenital or possibly a fall when I wasn’t looking. This “chest” hernia is something she will always have, and she has learned to live with – she gets tired faster, and she definitely chooses not to go up on high places anymore. (which makes me think it may have been a fall – or it just hurts her to jump up and down so she doesn’t do it)
I think bunnies can jump high, just not sure what happens when they slip and fall, not sure if their spine structure is set up for recovery since it’s rather fragile.
So, I wouldn’t take the fun out of her wanting to climb, but now I’m a even more cautious about the “daredevil” aspects and for me, the back of the couch is scary because most couches are much more curved there, and it doesn’t offer secure flat footing.
Again, I don’t know for SURE that Rucy’s hernia came from a fall, but since the vet said it CAN come from that, then I’m just offering a heads up ao your bunny doesn’t take a tumble down. Also we have hardwood floors, and even though we have area rugs with thick padding undearneath, it’s still not as cushy as carpet.
