I am hoping to get my male rabbit neutered soon.....so he can live with my female. But I was wondering what would you way is a good size cage for two rabbits? I have two mini rexes. One is a larger mini rex I would say 5-7 pounds and my female is a very small mini rex I would say 3-4 pounds. Also I am kind of scared about getting my rabbit neutered ....I am scared that some thing might go wrong. Is there a likely chance that something does go wrong? What are other people’s experiences with this? Sorry this is kind of long.
