Seems passive aggressive to eliminate your neighbors pet. I'm not a social person, and I typically let me neighbors do as they please (as I want them to do with me) but if I have a problem with an animal I'll approach the owner.
If my neighbor kills my cat and makes my kids cry without talking to me about it first, I'm probably going to create problems for that neighbor that involve the local police department.
