Just got a call tonight: "This is the humane society. Someone turned in your cat, Rowdy. " What's funny is, Rowdy wasn't even missing, as far as we knew. He was cuddling me at 3am last night. Apparently someone saw him out, thought he was lost and turned him in. They said he looked too well cared for to be abandoned, and checked and found his chip with our contact info. He's home now. Quite unhappy that I'm not letting him out to go rambling around the neighborhood again... Silly kitty.
