My ex brought home a baby which was abandoned when someone cut a tree down that had a nest of babies in it....Momma didn't have much of a mothering instinct and took off, leaving them.
We raised her until she was grown and became aggressive during breeding time. Then we put an orange reflective collar on her and set her free (we lived on 250 acres out in the country and didn't want hunters to shoot her).
She came and went as she pleased, but *always* came back when she had babies...easy food source. Over the years she brought MANY litters of babies around, and they'd all go down to the horse barn and eat out of the 55 gallon drums of corn we stored there. You'd walk in the barn and they'd be laid out on the rafters above...fat and lazy. If they wanted something different they'd come to the house for dog food.
One strange thing about her was that she loved votive candles.
Many times she'd come scratch on the back door and as soon as I opened it she'd HAUL it into the house, head straight for a coffee or end table, grab the first one she saw and HAUL it back out of the house.
Got no idea what she did with 'em, as we never saw any of those she snagged again.
Her name was Patches. Interior decorator specialist I guess.
