Sorry if i missed it but is the leg just broken or is this a case of splay legs?
I used to have a rabbit with splay legs, his hind legs pointing outwards, he had to drag his legs to move around but i hated to see him suffer like that.
I didn't live long.
And now seeing this rabbit it kinda makes me frustrated because it's obvious that he is suffering too, you can give him painkillers and whatnot but that still doesn't gonna help him to walk around like a normal bunny. He'll will stay handicapped no matter the help and care he is going to get.
I don't believe a rabbit can be happy when he can't run around and do the normal things that a rabbbit should be able to do.
I wouldn't want any of my animals to be miserable like this, how can you?
Don't get me wrong, i don't mean to offend anyone, sorry if i did. But i don't think it's okay and justifying to let this bunny continue his life with deformed legs.
Even a wheelchair is not gonna make his live better either.
