Most wild cats will live together in colonies to aid in survival. They will try to find refuge in abandoned buildings and cars and may dig holes in the ground to stay warm in the winter and cool in the summer. Much of their life is spent fending off other animals, disease and humans so they are not likely to cuddle up with you on your porch.
While not uncommon for both female and male cats, spraying of a urine mist is most common for un-neutered males. According to experts cats do this for many reasons. The main reason a cat sprays urine is to communicate with other cats. The urine has chemical substances called pheromones that aid in this communication. So, what are the cats saying? Being that the most common time to witness this behavior is during mating season, it could be reasonably concluded that the cats are articulating their availability to accept a mate. Spray also marks territory boundaries and is often witnessed in cats that are experiencing stress.
