From Craigslist ad:
An indoor cat got out on Thursday in the 400 block of Laurel St. in Oregon Hill. Black with white spots on chest and stomach. Red collar (may be gone) with tag with name “Oscar.” He has not come back and we have not found him. The sooner the cat is located and returned the more substantial the reward. If they have found this cat. Call me at 703-431-7778 or 202-450-7863.
I used to live in O Hill. Our cat got lost, and we wearched at dusk, according to some advice we read. We alos posted lots of signs, and we found him! I definitley suggest searching at dusk.
