Crat - a hybrid of "cat"and "rat" and is a term loosly used by people who consider "crats" to be on the level of street vermin, and take pleasure in exterminating them as such.
I stopped in a pet store to get a dog food dish to use to hold bullets while I am reloading. I like the rounded botton and the no-spill shape, plus they are cheap. An engaging little girl was looking at a cat in a display cage and asked me what kind of cat that was. I toned down my response since her dad was standing next to her.
I told her it was a very old type of cat known as a "target crat". In a loud and excited voice she proclaimed to her dad and all the other customers "That crat's a target!" I head for the check out counter quietly while the other customers were trying to convince the girl that the cat wasn't a target. She wouldn't believe them and kept yelling "The crats a target! The crat's a target crat. That nice old man told me so!".
