I can't disagree more with huntNH's response. If it's illegal to shoot that cat, you shouldn't do it, period. This website was set up to promote deer hunting, not to give advice that advocates breaking laws or taking it into our own hands. Vigilanteism, whether dealing with two-legged or four-legged culprits, is a dangerous path to follow and illegal for lots of valid reasons. There may be problems with some of our local game departments, but "Shoot, shovel and shut up", is a pretty sad way of dealing with issues that can be corrected in other (lawful) ways. At a minimum, being an ethical hunter means following the hunting laws of your state. Good luck with your situation.
