Cats...

• Cats sleep for 70% of their lifetime. 
• There are more than 500 million domestic cats in the world, with 33 different breeds.
• Cats "paw" or "knead" (repeatedly treading on a spot - sometimes its owner) to mark their territory. Cats sweat through the bottom of their paws and rub off the sweat as a marking mechanism.
• Cat urine glows in the dark when a black light shines on it. If you think your cat or kitten has had an accident in your home, use a black light to find the mishap.
• The print on a cat's nose has a unique ridged pattern, like a human fingerprint.
• If your cat is thrashing its tail, she is in a bad mood - time for you to keep your distance!
• If your cat is near you, and her tail is quivering, this is the greatest expression of love your cat can give you.
• Only domestic cats hold their tails straight up while walking. Wild cats hold their tails horizontally or tucked between their legs while walking.
• The more you talk to your cat, the more it will speak to you.
• A group of kittens is called a "kindle." A group of grown cats is called a "clowder." A male cat is called a "tom," a female cat is called a "molly" or "queen", and young cats are called "kittens."
• Cats can make over 100 vocal sounds, while dogs can only make 10.
• The majority of cats do not have any eyelashes.
• Cats rarely meow at other cats.
• When cats are happy, they may squeeze their eyes shut.
• The reason for the lack of mouse-flavored cat food is due to the fact that the test subjects (cats, naturally!) did not like it.
• Cats see so well in the dark because their eyes actually reflect light. Light goes in their eyes, and is reflected back out. This means that their eyes actually work almost like built-in flashlights.
