If you hit a deer with your vehicle, you can't harvest it and eat it. Not even if you use a tag from your valid hunting license. And, if you call the TPWD, they will come and clean it up.
But with dog or cat, no state department gives two shits. And they ain't cleanin it up. And it's legal to pick that damn sumbitch up and cook up some gumbo.
I was a teen driving in the wee hrs and hit a cow with my side mirror and knocked the shit out of that poor cow. Broke my mirror off on an old school Cadillac. I stopped to check it out and he looked like he just took a heavy weight punch from Mike Tyson otherwise appeared to be ok.
