Great pictures! Sometimes I lie down on the floor sometimes to take short naps and one of my cats would come around and I would place my head on its body (gently though). Besides the cat's purring, you can hear all sorts of sounds from it's belly region too!!
The current heat here is terrible. The cats would lay flat on the floor under the fan, and just sleep and sleep, to conserve their energy I guess! My dog is lucker in that he gets to go swimming.
