Thanks for all the clarification everyone. I used to be on RU a lot but since having relatively healthy bunnies (until now) and having our children I haven't been on as much and its surprising how much you start to lose some of your knowledge when you're not looking at it on a regular basis. So thank you.
Buttercup has had Zebedee by her side throughout and they will remain together all the time, Zebedee has been at the vets with her. I maybe won't disinfect everywhere then if that's an unnecessary thing which could stress them out away from their familiar smells etc. Wow, yeah I didn't think about that it could just take one insect.
DH took them for the RHD2 vaccine, which we had to fight a bit to get and he thought it covered them for myxi as well, but he often gets his wires crossed on these sorts of things! Perhaps we could get Zeb's combined booster done at the next vet visit then, and wait for Buttercup's booster until we get the all clear.
How often does the RHD2 vaccine need to be repeated?
Thanks all, much appreciated!
ETA: do we give the combined RHD/myxi booster annually if they have the RHD2 one, or just myxi booster on its own?
