Hello! Lola and Toboka have met a few times now (I can't get them together too often, I have little time to spare now that college is upon me) and things are going okay i think. Toby charged at Lola a couple times when he tried mounting her head, but there's been no real fighting.
I'm pretty sure Lola thoroughly approves of toby; he licks her a lot and lies down next to her, and today Toby licked him back a couple times but the humping is worrying me. I don't want them to move in together until I'm certain one of them won't get hurt, but how do I mark progress? Lola's castrated but Toby's not spayed, so I'm worried that's going to cause problems with Lola's instincts or something.
Any ideas? How much mounting is too much, and should I let them get on with it or separate them when they do it?

For anyone who's bonded bunnies, did you know when they could live together or was it trial and error? I'm super worried it'll be too much too soon and Lola will really hurt Toby :(

Thanks!
