I've known a few cats that were all affectionate until you gave them their morning treats. Then the rest of the day they didn't want to be bothered by humans at all.
Mine follow me and, when I stop to do something, they all lay around me.
I joked with a friend who knows my health condition that they're all bucking for jobs at an assisted living facility...
I seem to have offended her as she always finds an excuse to not visit after I said that.
