What if the cat looks like it was hit by a car? Don’t move it if there’s obvious injury. Document the scene with a photo (for your own records), then call animal control. The driver might be long gone, but you’re not in CSI.
And for the love of all things fuzzy, wash your hands thoroughly after handling anything. Even with gloves. You don’t know where that cat has been. It’s not personal—it’s hygiene.
Finally, give yourself a pat on the back. Finding a dead cat is a crummy bonus level in the game of life. You handled it. You were kind. And hey, maybe light a candle for the little dude. Or just binge a funny show. You earned it.
