She has line-of-sight to the entire room, and I've caught her tracking the betta on the far side so I know she can see to where the snake is going. Yeah, I'm probably going overboard, but I like to keep my critters as happy as possible. Especially her, since she didn't exactly ask to be made into a pet. (She came in with the potted plants in the fall and by the time we found her it was too cold to just stick her outside again.)
