Gargoyles usually live on rooftops, crouching above us, surveying the world. But sometimes people capture one and make it a pet. Like most truly wild things, gargoyles can’t be domesticated. (Never keep them inside. ). They aren’t friendly and even the most docile need to be restrained. It’s not comfortable living with a heavy, cold metal chain around your neck. Better to let them free to perch on your roof.
