One litter of kittens can be fathered by more than one cat. cats see red, blue and green. Cats spend about 16 hours per day sleeping. When your cat brings you a dead mouse etc. it actually is a present. A cat can jump up 5 times its own height. Cats can make 100 vocal sounds. When cats are happy they may squeeze their eyes shut. Just a few facts
Cats always land on their feet because they have a portion of their brain that is devoted to sensing whether or not they are in the upright position. This allows them to turn and reposition themselves almost instantaneously.
I know that while cats land on their feet their muscles relax making them able to fall tall heights. There was a story that a cat jumped off a 19 story building from a window and lived, with few injuries! They aren't known to be obediant like dogs. I had a cat that could open doors. They sleep at least 18 hours a day. And they are cute. Hope this helps! :)
