I have a never wavering rule at my house you mistreat my critters you are asked to leave then and there andasked to never return. If its a group (as yours was) all are asked to leave,they either learn or they don't really give a s**t about me and my feelings. My brother grew up knowing I'm this way and for about 2 months as a teen he wasn't allowed to visit my daughter couse he almost hit (with his car ) one of my dogs. He came flying in the drive not looking, he said later after the 2 months and aplosing his ears hurt for about 4 hours . I really laid in to him and pulled the coil out of his car and threw it in to a pig pen, he had to walk to the parts place and by another one. (I am a little less hostile now) We finally told my mom about this a year ago she wondered what had happened as he slowed down in there drive too.
