You have a warm heart, sparks! You will not
roast in hell, only be boiled.
I'm well aware of all you wrote, rest assured, but it's really completely different: it's one of my neighbors' cat, not a stray. Young and small, but extremely athletic and curious. And well-fed. And very, very shy.
We are first floor so the risk of the little bugger ending as a moist splat on the ground are slight, or I would have contacted these people. (Actually I told the janitor while we were having some Belgian beers together, so something will get transmitted and they will do as they see fit.)
It's really part-time (or time sharing?), he's free to explore and even rip holes in my dilapidated furniture (within reason), but I won't feed him so he doesn't switch staff.
Lousy pictures, but as I said he's very shy and I keep the room dark.
Oh, and I'm old and dumb, but not poor.
