The proper care of outdoor cats has become one of those issues — like tipping, or whether the toilet paper roll should hang over or under — that will no doubt incite flame wars until the end of time. That said, Lindsay in Oregon was still a bit surprised when this note appeared on her apartment building’s bulletin board, given that “FOUND” posters referencing the same collar-less cat had been posted on said bulletin board for weeks on end.

After experiencing similar problems with the neighbors (despite the fact that his cat already wears tags with his owner’s phone number on them) Elisa’s friend in Seattle had another tag made in hopes of preventing future trips to “kitty jail” — or at least to piss of the neighbors taking his cat there.

Just in case you were still under the impression that leaving an anonymous note will somehow allow you to maintain the moral high ground, take a look at this classic neighborly exchange from Drew‘s apartment building in Atlanta.

Part 2 in our “How to be the worst neighbor ever” series comes to us courtesy of Chris in Fort Worth, Texas.

When he first saw the note go up in his apartment complex, says Chris, “I thought it was pretty funny, but it wasn’t until the thief wrote a response that I had to take a picture.”

“My boyfriend, Alex, lives in a high-rise apartment building occupied by college/university students — people you’d think would have some intelligence,” says Meghan in Hamilton, Ontario.

Of course, a little learning is a dangerous thing. In Alex’s building, this seemingly civil request from one of the building’s residents garnered the following indignant response.

But Meghan says her favorite thing about this exchange is the placement — right next that big ol’ city-mandated “no smoking” sign.

Emma says this note appeared in her dorm at the University of Chicago shortly before the Thanksgiving holiday. “Our kitchen has a sign on the fridge that says: ‘If you leave your food unlabeled, it’s fair game. Label your food.’ I assume this girl did not label her food.” (Because who would be cruel enough to steal such a traditional Thanksgiving delicacy from an old lady?)

Another dorm resident sent in a shot of the anonymous response added later.

Our anonymous submitter didn’t catch the original note about “slaming [sic] the door,” but you can get a pretty good idea of what it said based on the carefully worded response from the recipient, John (who, like Dustin, simply isn’t aware of his own strength at times).

Meanwhile, this note, as seen by Felix in Atlanta, was clearly left by a neighbor without a law degree.

(I’m guessing a dog; cats are way more passive-aggressive.)

If you needed another reason to be happy you don’t live in Utah, Justin brings us this explosion of bad ideas from a Provo office park.

(I’m going with “Team None-of-the-Above” for this one.)
