Hello @manorvillemike: I hope you're lucky to get someone interested in Scary Mary; I do not know much about cats; but, it seems to me that a change of environment or another home would not favor Scary Mary. Maybe, we have to wait a little longer until Scary Mary reaches something more trusting with her family.
Greetings @manorvillemike
She is totally bonded with me. Guess I'm stuck with her.
