Many times, re the 'drop-in-for-food' strays, ferals.. one goes missing as in,
~4 years ago: the son (of one of current pair of In/Out ones): I had espied That one plus a drop-in who had become pick-up-able (!) since his first appearance months back: strolling down the entry road (to my cul-de-sac). instantly reminding of the ending of, Casablanca ..as Bogie plus Claude Rains, arm-in-arm are heading off --> into the sunset. Have seen neither since.. prompting Wonderings like, "hit by a car?" ...BOTH-at-Once/unlikely :-/ etc.

The Son was/is-still? intelligent, contrarian and perpetually in. action. {sigh}--so HOW? do you 'lose' two-such, from a sinecure with regular TLC+Food? [rhetorical]. Owls? I buffer this as: maybe they found an oasis in which the Staff-of-one: lavishes a better grade of rotisserie-chicken?

Glad your's ended the Worryings. (One of current pair would go-missing for a Day+, early on. Flashlights at night, run.. Fortunately Tux seems to have given up that, 'Way we keep the Staff confused' ploy.

It's all Show-biz, in the end: Break a leg!
