Our RSPCA home checker had no experience with rabbits at all, was a lovely lady, but normally just checked for cats and dogs! She had a list of things to check but really all she was making sure of was that there was a suitably sized hutch and run, that was all, it was far more basic than many specialist rabbit rescues would do, that said, all RSPCA's are very different, you might get someone who is a lot more knowledgeable!
:wave:
ETA good luck, don't stress, just make sure it is all set up ready rather than 'I intend to do this etc.' She phoned the centre the next day and then we phoned them after that and booked a time to collect our rabbit.
