Doug and I may have heard Jake! We caught a meow, a warning warble and then a yowl, all sounding like him and near the shed where a cat has gone to ground. Of course we raced outside, along with our other kitty, but we couldn't find him -- and it would have been creepy to crash around our neighbor's yard after midnight. But we are hopeful now!
[BACKSTORY: our tabby went missing from 127th St and 7th Ave NW on October 26. More info on FindingJake.com and the Facebook group Finding Jake!]
