Good to know. Then perhaps that snake had a viral RI.
Something I've been curious of lately, are viral RI's air-born? I have heard of people who consider a quarantine to simply be a snake in its own tub without touching other snakes. But, if RIs can become air-born then bringing a virally infected snake into the same room (even if it's in a different tub) will then infect all the snakes.
So - what do you believe is a good quarantine practice for those folks who don't have a separate room all together?
