Sykes was apparently getting out through a an attic hatch and an airvent in the roof, then it was down the outside of a gutter and the pillar it ran along (the slate/flatrock stuff that's meant to be uneven?)

he got stuck in my greenhouse when I replaced the paddle latch that he was batting open to walk out with a sliding bolt latch that he couldn't get open. Anyhow... poor guy was scared shitless and angry at the same time, by the time I found him. Putting out a box for him worked enough to get him down and home, at least.

There was also the window screen, the occasional door getting left open, the basement thingy. probably a dozen different ways that his family still hasn't found.

I get to watch him now, when they go on vacation (hence calling him my timeshare cat. I'm not at a place to have my own full time, but I can do a week or so on occasion.)
