Well, I killed the bird because it was just too tempting. You see, I’m Tuffy the cat, and I have a reputation to uphold. I’m a killer cat, and I can’t resist the thrill of the hunt. When I saw that bird fluttering around in the garden, I knew I had to pounce. It was a quick and clean kill, and I felt a rush of satisfaction as I carried it back to my human’s doorstep. Of course, they weren’t too pleased with my gift, but what can I say? I’m just doing what comes naturally to me. So, why did I kill the bird? Because I’m a cat, and that’s what cats do.
