During light sleep, the blood pressure remains normal, the body temperature drops slightly, and the muscles are mildly tense. However, during deep sleep (or paradoxical sleep), the blood pressure falls, the body temperature rises, and the muscles are completely relaxed. The hearing remains extremely sensitive, and a sudden sound will awaken the cat immediately. Cats seem to be able to fall asleep at any given time, at any temperature, and in several seemingly uncomfortable situations. Small kits sleep whenever they are not eating, and this is a key and important part in their development process. Newborn kittens spend most of their first week of their lives in a deep sleep, and during the next three weeks gradually have increased periods of being awake. Dreaming takes place during deep sleep, and cats will oftentimes twitch their muscles, growl, or purr. They may make lapping sounds and twitch their tail. It is most likely that during dreaming the cat’s brain sifts and sorts data for storage in its long-term memory. At least one third of the cat’s sleeping time is spent in deep sleep, and it seems to play an essential part in its well-being.[/style][/style][/style] |
