Cat Climbs Mountains And Desert Treks

Behavior
Free-ranging cats are active both day and night, although they tend to be slightly more active at night. The timing of cats' activity is quite flexible and varied, which means that house cats may be more active in the morning and evening (crepuscular behavior), as a response to greater human activity at these times. House cats have territories that vary considerably in size, in one study ranging from seven to 28 hectares (69 acres). Although they spend the majority of their time in the vicinity of their home, they can range many hundreds of meters from this central point.
Cats conserve energy by sleeping more than most animals, especially as they grow older. The daily duration of sleep varies, usually 12–16 hours, with 13–14 being the average. Some cats can sleep as much as 20 hours in a 24-hour period. The term cat nap refers to the cat's ability to fall asleep (lightly) for a brief period and has entered the English lexicon—someone who nods off for a few minutes is said to be "taking a cat nap". During sleep cats experience short periods of rapid eye movement sleep accompanied by muscle twitches, which suggests that they are dreaming.
