Keep in mind that urine can change in color due a variety of reasons, dehydration being one of the most common. However, urine can be discolored due to medications, certain foods (i.e., beets), or as a side effect of health conditions (i.e., liver disease).
These terms describe when an animal is most active: 1  Nocturnal - active primarily at night. 2  Diurnal - active primarily during the day. 3  Crepuscular - active primarily during both dawn and dusk. Many animals that are casually referred to as nocturnal are actually crepuscular.  Metaturnal - active part of the day and part of the night.
Found mostly in open and partially open savannah, cheetahs rely on tall grasses for camouflage when hunting. They are diurnal (more active in the day) animals and hunt mostly during the late morning or early evening. Only half of the chases, which last from 20 - 60 seconds, are successful.
