Sleep

Doesn't it seem that all cats are lazy? They need to sleep because it's natural. In the wild, they hunt all day then eat. They have to sleep to conserve (save) energy. Even though they get all the food they need as pets, they sleep anyway. It's a habit that all cats have established through the speicie's lifetime, cats wild, domestic, big, or small. They can sleep for ten hours daily or, in hotter weather, eighteen hours. And you know how people usually sleep more when they're, well, fat? same with cats! The truth is that the fatter a organism is (most likely from the Kingdom Animalia), the more energy it takes for it to move. Think of it like carrying a pillow. Easy, right? Now carry around a stack of wood. It takes more energy the more you have to hull around. This is for all the people who wake the cat up to play with it...... LET THE CAT SLEEP! :)
