Perfectly valid point. It would be very easy to pass something from one snake to another if a bug is present. This is where quarantine comes into play, I am not bringing in new animals all that often and when I do it is kept away from main collection for a period of time (search for quarantine to find all sorts of suggestions). Still there is always the possibility that an animal could look healthy and have something transmittable(sp) that and I'm clean hands freak.

Also I've worked in public schools for quite a few years now that I find myself washing my hands without really thinking about it.
