I know that pain to some degree. More than once, when life seems particularly stressful, the car will not start (or suddenly catch fire as once happened to me on the opening day of one of my plays!)

... and the cat piss ... the box must've been really bad for him to climb into bed (and cats know when their humans are particularly tired and wretched) and piss there. damn. I remember when Persephone (the wife) was on the eve of her year long stint to Japan we were having a mushy evening at home when Aleister (the cat) begins to act oddly. He's crouched on some pillows and glaring at us -somewhat defiantly-. "Is he peeing?, It looks like he's peeing!" I go and pick him up, and lo and behold: he's peeing & he's not stopping. Cat pee fountain all over the oriental and pillows (and me).

I think he was stressed about the up-coming change.

So, I don't know, carry on and be well.

(however, I do love cat stories!)
