You don't want to know what I think you should do with it. Squirtbottles would work, too.
I also hate the fact that there is all this talk of an "outdoor cat" vs. an "indoor cat." I'm sorry (no, I'm not) people, but if you want to get a pet then you need to take FULL responsibility for it, and buying a cat that lives outside and comes home every so often is not doing that! Cats kill over 1 billion, that's BILLION bird a year in the U.S. alone. Many of the small bird species that they kill are endangered, but they don't stop there. They also kill herps! Small lizards, geckos, frogs, toads, snakes, etc. If you buy a cat, keep it indoors and look after it, period. Your local ecosystem didn't evolve with cats as a predator, so spare it from your cat by actually being a pet owner.
