My cat, Pris, is always bringing in lizards. I generally find their dried, shriveled carcasses when cleaning I will occasionally find a live one which I attempt to free. I've found one with his side ripped out and his guts exposed. I found him yesterday but lost him because Pris found him before I could do much else other that note the severity of his wound He's resurfaced, he's still alive and currently making a run for the door. Do I leave the door open and hope his wound is not as mortal as it looks? Do I actively free him? Do I kill him quickly? If so how? Drown him in the toilet? Drop something heavy on him?
