I cannot say what the time was exactly (most likely between 10 and 11 PM). I was in the house and saw only the end of it though my picture window. I've seen several of these things over the years, but didn't realize I could report them. Next time the time will be better.

Remarks
I heard a sound right before I saw this through the window. It was similar to the cat jumping off the patio railing and landing with a thump on the deck, although I thought it was a bit loud for an 8 lb cat and I couldn't say if this was a coincidence.
