When I first started I kept rats in the same room as snakes for about a year, once I moved the rats out I kept a bunny in the same room as my snakes....for the past 6 years it's been snakes only in the room however I never had any issue during the years fury animals and snakes were housed together.
The important thing if you keep small fury animals and snakes together in the same room is not to have them out at the same time, wash your hands between handling and make sure that all enclosures are secure and no one can escape.
