Cat scratching? No. Interesting? I think so.

It's a little hard to see, but the bundle of fur in the middle of the picture on the deck railing is a gray squirrel.  We have many here in Brookfield but this one did something I've never seen before.  It took a nap. 

He or she stopped the usual running and leaping that characterize these rodents; bent forward radically, appearing to grab its hind feet with its paws; and went to sleep. 

The day was rainy and overcast so the light was poor and the picture isn't great.  Didn't want to use the flash for fear of scaring the critter away.
