Indeed, my cat is fascinated with the garden snails & I can't have the cage & cat left unattended together. I came home once to find the cage tipped on its side & all occupants unaccounted for. Then had to grab a headlamp in order to trace the shiny trails to locate almost everyone that afternoon. Unfortunately that didn't work for all who fled because Monkey played soccer with some of them on the hardwood. I did eventually find everyone but it took a week for the last snail to be recovered (with Monkey's help no less) & no one's shells were severely damaged/none of them died thank goodness.
