Bobcat and Lynx are making serious inroads into settled areas. I'd be careful about "coaxing" the critter. Get a good look at it if you can to be sure it is what you think it is. The "cat" we had in our crawl space when I was a wee tyke turned out to be a rather aggresive Opossum. Had to get animal control to trap and remove it.
Well, it appeared to be the hind legs and tail and back of a yellow/orange striped tabby type cat. I didn't see it's face, it was too busy trying to scramble under the porch, and it took it a few minutes.
John said to watch for a couple days and make sure it's a) a cat, b) not wearing a collar, and c) really living there and not just diving under there to hide from me yesterday.
I'm afraid to try and coax any creature I don't know, I had enough trouble trapping a hurt pigeon last year for Animal control, and also dealt with a crazed Raccoon that I wasn't happy about who suddenly fell out of our tree. (Fortunately, I never had to catch him, Animal Control came and tried but lost him down the sewer).
I think the flea powder will hopefully prevent the flea issue from reoccurring, and I've tried asking around whether anyone owns this cat, but I don't know but two of our neighbors, really.
Thanks for the suggestions, though Scott, we're keeping everything in mind.
