Cats are usually nocturnal, or active at night. They will get up early in the morning and have a "play time." (My cats always do this when I'm trying to sleep.) Afternoon is nap time. Play can consist of pouncing on toys, on other cats, on leaves, or any other moving object. Some cat play is actually practice for hunting.

When we think of cats, we usually think of pets. However, there are many feral domestic cats running around. They can live singly or in colonies of cats.

A single sharp claw mark shows above the left outer toe in this perfect cat track. Perfect tracks are hard to find. You have to have almost perfect soil conditions. This was river silt, left behind after the high water had receded. The track looked the same one week later when I returned to plaster cast it. All the features that identify this as a cat track are clearly visible. For more about differentiating cat and dog tracks, see Canine vs. Feline .
