When I got to work this morning (office at in-laws), my M-I-L came out asking if I'd seen the cat in the grass. Sure enough, there was a small-ish domestic appearing cat just sitting in the grass, meowing. He let me approach him, then he walked/sauntered/waddled up to the driveway area and laid down again. I used a stick to turn him over, noticed his balls and assumed since he's a dude, he's not pregnant. I load a bolt action .22 and set it by the work van just in case. I had my work gloves on so I grabbed him by the nap of the neck and near the tail to take him to the grass and once I set him back down, he started hissing and doing some crazy dance like we were going to fight it out. Then he chilled out and moved towards a close woodline. I figured he had rabies so I mercifully put him down with  shot to the back of his head. Now, I threw my work gloves away, washed my hands, disinfected the rifle, safe, doorknobs and what not. Should I burn or bury the carcass?
