Well… vets have been wrong before. But assuming you have one of each, I would say that it is unlikely they won’t attempt to mate at some point. The problem is that it can happen in literally seconds and it will be too late. Letting them play together is asking for trouble.

As LBJ says, it can happen in literally seconds. I know a dog-trainer who thought she’d be able to intervene if a male dog tried to mate with her female dog that was in heat. She wasn’t successful, and those were spaniel dogs, rabbits are even quicker.

I don’t think it’s possible that two rabbits of opposite sexes wouldn’t try to mate. There are a few congenital anomalies of the reproductive organs that can make mating more difficult or even unsuccessful, but it’s nothing I’d count on. We did have a member who had a cryptorchid bun that couldn’t be neutered and who was successfully bonded to a spayed female for several years, without a humping-problem, but I’d not bet on it happening very often.

Keeping them separate is very smart of you, and it will not just prevent them from making babies, it will also prevent them from getting into a bad fight once their hormones come on strong. Any bad fighting will lower the chances of the buns ever bonding properly once they are desexed.

It’s honestly possible and even likely they have mated already, it can happen in a flash (even through cage bars), and once it’s happened they won’t keep trying…. Females can get pregnant as early as 12 weeks. You can check to see if your male has “dropped” as well.

I would stop letting them interact during play time at all. By the time you would be able to intervene it would be too late. If they are kept side by side they won’t forget each other!

Not trying to be alarmist, just don’t want you to end up with an accidental litter (or take her in to be spayed and they find she’s pregnant).

Very cute floofs!

I agree with all of the above.

My thinking is it’s very possible they aren’t in full puberty mode yet. When I had mine through puberty at about 5 months they were showing the signs, circling, honking etc, I thought that was it, I was just waiting for them to grow enough to be desexed.

Then at 6/7 months they Reallllly hit puberty, it was very different and the behaviour became pretty intense peeing everywhere and destructive.

This actually happened with two of the rabbits I’ve had at different times as they weren’t litter mates and were a year apart in age.

Just my thoughts, I think its very rare for animals not to show the instinctive and natural behaviours we expect.

It is more likely that neither of them are at this point experiencing hormonal urges. Some rabbits experience it later — for example, my Wick did not display any hormonal urges until he was 8 months old. A baby bond (which is what they have) is considered a temporary bond expected to dissolve once at least one of them begins feeling the hormones more, which is often a whiplash to many owners because baby bonds can seem very legitimate and secure for the months they exist. Again, they might just still be too young at this point. Continue separation and assume the baby bond will eventually end.
