Cats are bizarre creatures.
some of my cat's rituals and oddities:
-when we first got Marco, he was perhaps a month old (feral kitten, found in the middle of a busy street). For a solid six months he would go in the bathroom and do the nursing thing on the rug (hold it in his teeth, push/pull with his front paws.)
-when he was about 2 or 3 someone gave my wife a fleece and flannel blanket as a gift; we kept it on the couch for chilly nights. At various times we'd catch him, umm....violating it. Yes, I mean that violation.
-he has different meows for different situations. My favorite is the one that greets me every evening when I get home from work. It's pathetically high and mournful, I assume to convey "I haven't eaten in 9 hours, and boy, all this sleeping and licking all day takes a lot out of a guy!" The meow then becomes all weird and drooly as I put the food in their bowls.
-He loves playing under the covers as we make the bed, as I suspect most cats do.
-He loves hellish heat. The radiator in our living room has a big enclosure which acts as a window sill. When full up the heat turns this surface into a griddle suitable for preparing eggs and burgers. Naturally, he lays on this for hours at a time when it is fired up.
-Heat from other sources is also relished by His Majesty. While holding him in his preferred position (flopped over my left shoulder), he loves when I put my lips on his neck/shoulders and blow (builds up heat)....instant increase in purring and activation of the push/pull thing...ow; watch teh shoulder, kitteh!
-when in same position as above, fascinating purring variations may be achieved by gently squeezing during feline exhalations.
