That looks like it is all going really well. I left mine all together day and night, but they were in my bedroom so I could easily hear if anything was going on.
Oh dear, another frantic 5 mins with Neville chasing trying to hump (the wrong way too ) and Susie looking quite unhappy and making some little noises.
Can anyone advise on when to step in? I'm stopping him a lot but I'm wondering if it's prolonging it? It's just he keeps going at it the wrong way round!
If he's humping her the wrong way around you do need to step in because it would be very easy for her to bite him and cause serious injuries.
Oh and to add - with this in mind, would you split the pen overnight?? I'd rather go slow than have them fall out or get hurt...
I'm sleeping in the same room.
Aside from anything else, I would be wary of increasing space to early. And when you do, increase very, very minimally. We usually section off with propped up cardboard as a divider - very makeshift, so supervised.
It sounds to be going well for you - certainly compared to some of my bonding rabbits! Good luck
