Where o Where is My Cat?

A reader writes:

If any of your readers know someone who lost a black cat with a pink collar and bell, the poor thing's on Museum Campus and terrified as all hell. I tried catching it but would probably need a more concentrated effort to succeed (trap and food, or friends who can help me corral it). I've seen that same cat a week or two ago -- it looks young and I'm concerned it's not going to last long. I did report it to Chicago Animal Control, but maybe someone here knows what else to do?

If this does happen to be your cat, email me (or post a comment) and I'll tell you the exact location from tonight's sighting. If you want help catching it, I'm willing to give it a try.
