Some years back, a little family of squirrels got in to our attic and made it their playground. After the outer hole was patched, I began humanely trapping and releasing them with good ol' peanut butter as the bait. I then had the idea to add some white spray paint to their backs, to make sure they weren't still getting back in. Actually I only tagged one squirrel that way, as it just... well, something felt off about the process, and I only needed one test subject, I thought.

A couple weeks later I saw a squirrel running around with a lot of its back-fur missing, and realised that I'd F'd up. Fortunately (I think, I hope) that given it was summer, the little one would have plenty of time to 'fur-up' before winter.
