You should wait until both bunnies are spayed and their hormones have had time to settle before working on bonding them. At this point their hormones will keep getting in the way of the bond forming properly, so best to just keep them separated for now.  Unfortunately this is a common thing that happens when babies are put together. They get along until they hit puberty, and then they often start fighting. For now, giving them some cooling off time with no bonding sessions or pre-bonding is prob a good idea.

I think I would wait until about 4 weeks until after MoMo’s spay, and then you can do some pre-bonding (cage swaps) to help them get re-acquainted with each other’s scents. If they seem calm with cage swaps and living as neighbors, then you can start bonding sessions in neutral territory.

That must be a relief!

Bathtubs seem to work well for some people. I wouldn’t use a sink though, if they jump out they would likely get hurt.

I agree with what’s been said above. 🙂

Bathtubs or couches both work. I did my neutral bonding sessions on a couch, but with a pee pad under them. 😉

Oh yeah, sorry I missed the question about the tub vs. sink. I think the sink would be too small, but tubs can be great. Or the bathroom floor if you want to give a bit more space.

I think setting a room aside now is a great idea. And then on top of that, you can get a sheet of vinyl flooring or a plastic tarp, and put up an x-pen with blankets on the sides to be the bonding space in that room. That way they won’t recognize the floor or be able to see where they are. I know of quite a few members who have used that technique to create their own neutral space for bonding.

That’s great! Keep an eye on attempts to jump or climb out. I’ve never seen bunnies jump as high as when they are trying to “get at” a bun in another pen.

Are you asking if the construction in the basement would be too scary to do bonding sessions on the second floor?  It depends on the level of noise… but some stress from the noise might actually help the process. Of course you don’t want it to be too intense, but I imagine being a couple floors up it would be a bit muffled.

Behavior mirroring and laying near each other is a very good sign!

If the stress was very intense for a prolonged period of time, that could be harmful. I think the only way to know would be to try it out. They might get used to the noise if it’s not too intense. You could certainly try some shorter sessions in that space and see how it goes, or time the sessions so they are after the workers are done for the day. If you start getting into longer sessions (like more than 3 hours), even in a non-stressful space, you should make sure both buns are eating and pooping relatively normally.

Does it seem like there is lots of dust upstairs? Is this in a house different from where you live?

Ok gotcha!

I like the 24/7 method, but I usually like do at least a few short sessions first, just to get a sense of how things will go. And of course have back-up plans in case it’s not going well. There’s nothing wrong with taking some breaks if you need them (or especially if the bunnies need them). If you’re going to do it alone, it can be hard to supervise 24/7 for long periods because you eventually need to use the bathroom, eat, etc. But maybe you have a support crew? 🙂
