My husband and daughter were taking care of Bella for a few days while I was out of town. When I got home I found that the timer on her light had been unplugged - I think one of my daughter's friends unplugged it to charge her phone . Heating was untouched and they were good about cleaning up after her. Bella seems fine, but what could the effects of that have been? She's in a darker part of the house for the winter so really relies upon those lights.
