The boys have been pretty active in the last day or so, doing everything from cave diving into a new briefcase I was transferring stuff into and playing on the couch with computer cables I was organizing, to jumping on the bathroom window sill (the only window open during some rain).
(Or maybe it's their normal level, and I just have not been paying attention.)
They also both visited the dining room table. In response, we demonstrated to them that the Mist of Doom lives. (Okay, we used it on them.)
Their youth and vigor remind us both that some do live well past their prime, and that our kitten farm remains very well stocked.
