Hey, I'm not saying I wouldn't alter a rabbit if I got one. I'm not saying I would either.
What I AM saying is the oft quoted statistics promoting altering in rabbits are rife with some seriously eye-brow raising issues, and that does not speak well for the cause. The particular "statistic" I quoted earlier, with its extra variables, is nothing short of propaganda, in fact - twisting information to promote a cause.
If someone was asking me about altering a rabbit I'd be all about it if it were female and all it was wanted for was a pet, I could go either way with a male rabbit - the boys ime were friendlier although yeah... they did spray pretty frequently. I had plenty of female rabbits hit about 5.5 - 7 months and turn into a ball of **** rage and viciousness - except... when they were pregnant. If the goal is a housepet - imo not much would be better than a female rabbit that was spayed.
I had a very nice dwarf hotot doe. Beautiful type wise and just a pretty rabbit. She was the most vicious rabbit I've ever encountered. She would just snarl and growl as you walked by her. Once you got her out of the cage she was fine - when she was bred - she was the happiest friendliest critter on earth until you weaned her litter. Then back to grumpy pants.
I didn't really notice any distinct temperament traits among breeds of rabbits for the most part except with the checkered giants. A nastier group of rabbits I am not sure is in existence. Every single one I dealt with was a snappy biter - in or out of their cage. My friendliest rabbit was a holland lop but I can't really say all or the majority of holland lops were people friendly. Many were, many weren't. They really did seem to span the range.
Now just as a disclosure. My rabbits weren't housepets for the most part except for a couple special ones who received pet status - Albert, Calvin, and Licorice. They were for 4H, for ARBA competition, and failing those two roles they were for dinner or snake chow.
