Besides my two lovely dumbo boys, I have two fancy mice (Lily and Olivia). Olivia is just a DREAM pet super friendly and content as could be to remain in her cage. Lily on the other hand is intent on escaping from her home. She has managed to get out on MULTIPLE occassions and it scares me to death! (we have a large black lab in the home who would find her to be an awesome squeaky toy ) Other than staring at the cage for hours trying to figure out where shes escaping (which I have done multiple times) what can I do to discourage her? I would hate to have to put her in an aquarium but I'd hate even more to come home to only one mouse. Anyone have any suggestions?
