Nope! Just decided to be a disappearing asshole for 36 hours and come back like nothing happened.
edit: thanks to all for the different perspectives. he is fixed, has all of his shots, and has his own temperature contolled kitty condo (aka the laundry room) that we put him into every night. we have a pretty good network of neighbors and pieced together his activities via security cameras. he's a mouser for sure and that is his job until he decides to retire.
For my cats we were lucky enough to live somewhere that had very little traffic at the time, so we'd let the cats out only when we were out.
Then slowly let them out, but only in the garden area, and then only with a leash. Eventually we stopped letting them out. We'd distract them before opening doors.
