A fugitive, who less than a week ago was behind bars, left this note in its place ... spiting its captors.
The note reads, "You underestimate the power of the squirrel. Try to catch me again, I dare you."
It's signed "Scrappy" and yes, it is supposed to be written by a squirrel, to the owners of this west-side Madison home.
The owner of the house didn't want to go on camera for fear of retaliation ... not from squirrels, but from their neighbors ... who police say, are more than likely the real authors of this threatening note.
"Someone had the gall to come into their yard, remove the squirrel and then leave a note too," said Mike Hanson, Madison police department.
Apparently it was the love of squirrels just like the one's that were running around the capital square on Tuesday, that led someone to release the trapped squirrel and put a note in it's place.
The animals are causing the family that lives in this house enough grief to pay a pest control expert to live-trap the squirrels, so they could be moved to another location.
According to the family, it costs $100 to bring the pest control expert out, $75 to set a live trap and $50 for every squirrel that's removed.
That's why police say this might be one of the strangest trespassing calls they've ever gone on, but it's no laughing matter.
"The bottom line is, someone had a squirrel problem in their yard, they tried to fix it and then somebody came and added to the problem," said Hanson.
In the meantime, the family says they've left a note of their own, warning the squirrel sympathizers that they mean business, about getting rid of their rodent problem.
