Craigslist? What am I doing wrong?

I put an ad on the Macon craigslist about two weeks ago for 4 of our adult cats and the 4 kittens. Got a call wakin us up at 3:30 the next mornin. The guy said "I want all the cats". I said. Ok. He says You ever seen my web site "kitty ****.com?" I said a few choice words to him and slammed the phone down. At one time in my life, that mightta been funny, but right now, with Kitty workin her *** off and needin all the rest she can get, it was not. I think all some people live to do is "F" with others.

Oh and since then, we decided to keep all the cats. If we go down, it's gonna be all together.
