I used to work in a cat and rabbit rescue and just used to wash my hands and change my clothes when I got in, more often then not I'd hop straight in the bath/shower. But that was only because spending a whole day with cat litter trays makes you kinda want to wash and have clean clothes!
I didn't stress over it though, if I didn't change the instant I got in I didn't worry, my work shoes were in the hall and got sniffed regularly by three bunnies with no issues. I did start being over cautious when a bun at work ended up with myxi (he was vaccinated) then my shoes stayed in the car and all clothes went into washing machine and me into shower when I got home.
I did not bring anything home with me though... well except Poppy the bun, and Sugarplum the guinea pig, and the 4 little 2 day old kittens, and then the other set of kittens that had lost their Mum... all but Poppy went back though :lol:
