I’m no expert so take what I say with some salt but I wouldn’t do any kind of playdates if your rabbit doesn’t like other buns, even if they do I wouldn’t recommend it. You never know if or when a fight’s going to break out and if the bunnies bond then you’ll be taking them from their bond mate which, from what I heard, can make them very anxious and depressed and can make them act out. Personally I’d just avoid it all together.

A couple of things, rabbits can’t do play dates. They form bonds where one rabbit is usually dominant to the other. The bonding process can be long and difficult and once bonded rabbits shouldn’t be separated. The most likely thing to happen in an attempted playdate is fighting between your two rabbits.

In regards to the guinea pigs, they won’t make a rabbit sick but rabbits can carry the bordatella bacteria which commonly causes respiratory illness in guinea pigs, so it’s not wise to put them together for health reasons, plus also safety reasons given that they communicate differently and have different social structures.

So,  “hoppy hours” are a little bit different, but they also come with some risks. Meeting other buns at their house is not a great idea because if they are anywhere near the other bun’s home territory it can cause fighting, as the others have mentioned.

At hoppy hours and Bun fest, they have a huge area set up and lots of trained volunteers that are really good at preventing fighting. There are also so many rabbits that the buns don’t really behave the same way as if they are in a smaller group. But fighting does still occur occasionally, so rabbits that are known to fight get removed. The hoppy hour my rescue used to put on had “bunny bouncers” and extra pens set up for any buns that weren’t doing well in the big group.  There is also some disease risk, especially now with RHDV2. Idk where Bunfest was supposed to be, but it’s possible it’s been cancelled or paused due to RHDV2.

I’ve taken a couple of my buns to hoppy hour, and one of them had a nice time (she just laid around, explored, and ate grass), and the other bun hated it (he just sat in the corner and pouted).

Since you mentioned your bun doesn’t really like other bunnies, I wouldn’t worry about taking him to socialize. If you are really worried he’s lonely, the best thing to do would be to bond him with another rabbit, or you can try giving him a stuffy to cuddle with.
