My snakes have always shared my entire home...every room (except kitchen, bathrooms & laundry) has some snakes in it. I have always done it this way...animals are
part of my life, not shut away somewhere in a room by themselves. And because they are so spread out, there is less chance of all snakes catching something from each
other. (there are pros & cons either way, of course) But this way, as with yours, they do get seen on a regular basis. Even with good intentions, it's easier to miss
things when your snakes are out of sight either in tubs/racks, or in another room.
