As I was packing up to leave for work today, I heard a sad mew out in the hall.
Whitey, the owner of the mew, padded into my office, wrapped himself around my legs, and gave me three more soft multi-syllable chirps.
I don't speak domestic tiger well, but I took his chatter as a query from a somewhat lonely kitten asking where his daytime human was. Her office has been empty for days now. Not much I could say to him in return, but I did pass the message along.
She can console him in person tomorrow evening.
