I have. My cat Midnight got attacked by a bobcat and somehow made it back home after missing for 2 days completely torn, mangled, an ear was missing, An eyeball was semi-popped out of the socket,full of deep, bone-visible lacerations, and the right leg was obviously broken. I was hysterical. I knew that there was no saving her. She was the sweetest cat I've ever had.
I gently picked her up, wrapped her in a blanket, put her in an open box, grabbed a .22 pistol, and put her in my car. The whole while i'm tearing and saying it's going to be ok sweetie. We go to a dirt road outside of city limits and I set her down. I keep talking to her telling her how much I love her. I couldn't see her suffer anymore. I gently petted her and wrapped her head with the blanket, took out the pistol after saying a prayer, and shot. I shot my fucking cat. after I did, I was so lost. I just sat down.
I re-wrapped her in more towels, picked her up and put her back in the box and drove home. I made a very nice grave and put all of her things (Toys, 1 Oz. bag of Catnip because she loved to get stoned, heh.) and said another prayer. I was so lost for about 2 months. I never realized how much happiness an animal could bring to someone, and how so much pain they could bring someone when they die.
Good job, BL. You made me all teary-eyed and shit. Makes me feel like a puss, and I'm a guy!
