(Anyone rejecting this post again is only choosing for cats to die more slowly and painfully. Care enough to even think?)

No no no no. Don't use a head-shot. Out of the hundreds and hundreds that I had to shoot I didn't waste even one bullet by aiming for a vital organ in their chest. They always died in under 3 seconds, often one second. Most so fast that they didn't even bleed-out. But one time I thought I'd use the often suggested head-shots on one of them. A precision shot to the head just above and between the eyes didn't kill it. It took 3 more point-blank shots to the head before it would die. (Who knew that a cat's brain is not one of their vital organs. Surprised me!) I never repeated that experiment again. Not only did I have to hose-down the area to disperse all that diseased offal of cat-brains so wildlife wouldn't track though it, killing even more wildlife after its death, but I ended up wasting 3 more 1/3-cent bullets on just ONE cat! What a waste of good bullets.
