hello im not sure what to do? i have 2 sister rabbits who are healthy and happy and get along but recently one of them has started to be a bit grumpy towards her sister and me! she is a bit of a pain to get out of the hutch and when i go to get her in from the run she will stand up on her hind legs and goes to bite me, she then has to be picked up by the scruff. I was just wondering if spaying would help and if she was spayed would her sister have to be spayed at the same time? xx
