It's about time!!!
Just kidding!
I remember you talking about that squirrel right before the season ended and deciding what to do..
I'm not sure if you and the wife are into feeding the birds and other wildlifearound the house. You might want to just put out a feww corn cobs or sunflower seeds around to just keep it around.
Squirrels love sunflower seeds. I'm sure it would always be hanging around if it had free meals available. Hopefully it will pass on a few of those genes.
I feel you'll have much more enjoyment seeing it "Alive" around the house. It would make a neat mount but I think you'd sorta regret killing it. I think you know where I'm coming from
