Maybe Kenneth knows.
Good one!
As an idiotic sometimes handler of dangerous wildlife, I can honestly say that this woman is nuts!
All the feel-good psychobabble does not negate the stupidity of...
1) leaving a back door open.
2) recognizing that a Wild Animal Apex Predator is in an enclosed environment with someone throwing frequencies at it.
3) failing to realize that if that big cat "felt safe and showed no inclination to leave" it probably considers the home its territory and knows where to come back to should it be injured or starved and needs somewhere "safe" to snack on hippy chicks.
If it was me, I would've closed that back door, taught that cat whose house it was, gone to the hospital, gone to the pet store for an XXXL litter box, and settled down with my new pet.
