I’ve been volunteering at a rabbit sanctuary for many years, during which time I’ve had various rabbits in my own home. I would always wash my hands and take off my shoes before interacting with my rabbits, and I would usually change my clothes since they might be dirty or sweaty, but there have been times when I’ve not changed my clothes or showered right away, and there have never been any problems with my rabbits picking up any bacteria, parasites or diseases, and they have never gone crazy from the scent that I might have picked up from other rabbits. I rarely pick up any sanctuary rabbits unless they need to be relocated for some reason, so their scent would be more likely on my shoes or socks or the bottom of my pants if I’m wearing long pants, or on my arms or sleeves if I pet them. I clean out their yards so the most contact I usually have would be when one of the friendly ones (some are wary of people due to past treatment) come up around my shoes (to possibly nibble on laces) or brush up against my socks or the bottom of my pants, and want to be petted. My shoes are kept in the garage since they are old and dirty. I have heard some of the other volunteers say that their rabbit reacted to the scent of other rabbits on their clothing, but it was never a violent reaction. Just interest and curiosity. All of my rabbits would just give me a few sniffs, but that’s about the extent of their reaction.
There are some rabbits that come into the sanctuary with fleas or lice or mites, but they are being treated and they are kept isolated, so I don’t really deal with them. There may be others in the health care building with respiratory problems, and I may give them a pat or two, but most of the rabbits in that building have chronic conditions that aren’t contagious, so there are few worries of bringing anything home with me, and I never have.
