I'll keep that in mind, thank you. Luckily I wasn't planning on getting any more snakes for at least another year, until after I move.
As for the cats, I do lock them out of the room when I'm handling any snakes - they just sleep with me in the room at night and can't reach the cages even if they tried to because of the stand heights. I suppose the snakes could smell or see them if they look down, though.
