The first picture is my Chinese cricket cage made out of bone. The Chinese value crickets as pets for their luck, song, and fighting and consequently bone cages costing $30 - $1000. Chinese crickets are bigger than Ohio crickets and I can’t use the cage with Ohio crickets, because they would walk through the bars. But in the last picture, now one can have the same good luck with Ohio crickets in a cricket observatory made out of 2-L soda bottle. The 2-L soda bottle cage costs $1 for sand. It is neat to hear them singing from their cage on a window sill.
