Thanks for rescuing these two bunnies – they sound like they got lucky!

It’s great that you got them both spayed – that’s the first step to bonding!

Dividing the room in half is a good plan, but make sure they can’t touch each other, as bunnies have been known to fight and bite each other through bars. My own little Atlas got a nasty bite on the ear from Luna through cage bars.

Peeing and pooping along the fence is normal – it’s territory marking, so you’ll often find bunnies peeing and pooping along the edge of dividers to mark space as theirs.

I would say the next step for you is to start swapping them between halves of the room, so neither sees either half as ‘her’ territory, and so they get used to each others scents being in the area where they live. They might well be angry at the beginning. Do this for about a month. Hopefully, by the end of a month, they won’t care about the swapping anymore, and you’ll start to see them do things like lie alongside each other through the fence.

At that point, you can try introducing them for a short amount of time in a neutral space I’m happy to help with that part later

Yes it sounds like you are off to a good start, everything sounds normal so far!

Box habits should return once they are bonded, and marking will hopefully go down once you do a bit of pre-bonding (swapping who’s on what side).

Running the fence and scratching at it are aggressive behaviors (which are normal at this point), but you’ll want to see those behaviors go away before you start actually dating them.

During prebonding you can also start swapping scents by brushing them with the same brush.
