Oh, man… where do I begin? Ok. So I’m adopting an intact senior male rabbit in the very near future, and I found a rabbit-savvy vet in my backyard who neuters and spays rabbits regularly. I always intended on neutering my future bunny, but now I’m considering on altering him to make bonding a second bunny easier.
Why did I decide to have a two bunny household? This gorgeous girl from my local pound:

I mean… how could you not love that face?
I completely understand that rabbits must be quaranteed at least two weeks before introducing them to each other, that both bunnies should be altered, and that male rabbits should wait about one month after neutering before being introduced to an intact female.
But are there any recommendations about how long I should wait after a spay before introducing a female rabbit? I mean, would any additional stress significantly inhibit her healing time or not?
My second question is about how to seperate two pre-bonded bunnies. I currently have a 3x3x3 NIC cage and I figured that I could just make a divider in the middle so that it’s essentially two cages stacked on top of each other, and I could always convert it back into one mega cage when (if?) bonding is successful. Is this acceptable, or would it be more ideal to seperate the bunnies into two seperate rooms before they are ready to bond? I’m assuming that both bunnies are not litter trained yet so they’re going to be poop bombs one way or another, so that’s not an issue. 
Finally… I’m completely assuming that the bunnies I’m planning on adopting are properly sexed. I know you Binky Bunny forum-goers have loads of experience under your belt, but any same-sex bonded anecdotes would be appreciated while I prepare for the worse.
