My husband called me at work yesterday to let me know Emrys' tub fell off the shelf. Luckily there aren't any decorations in there to bash him in a fall, but I felt so worried about him. He was fine, if a little wet and cold from his water spilling everywhere and being off the heat pad, but he's okay. I don't know if one of my cats knocked it over or if he somehow managed to, but either way I've got it tethered to the shelf now with some ribbon threaded through the back holes and tied to the shelf. I can't wait to get a proper rack so I don't have to have my snakes just sitting on a shelf.
