Stoves must be a BP thing. When I upgraded my boas to 4’ Vision cages, I put my ball in the larger of the reptile tanks...the one with the sliding latching lid that had been secure, so I thought. My boa had been in it for 2 years with no problem. Within 24 hours my ball had escaped. We were in that first apartment, and came home from work to an empty tank. I had visions of a loose snake that had slithered into a neighboring apartment showing up on the six o'clock news. We only had 500 square feet and we must have turned that place upside down. We finally found him under the stove, wound around some type of brace or bracket. My other half titled the stove back while I stuck my head and arms under it and unwound the snake. Everyone got locking cages after that.
