Pet
Sitting:
A pet is an animal kept for companionship and enjoyment, as opposed
to livestock, laboratory animals, working animals or sport animals,
which are kept for economic reasons. The most popular pets are noted
for their loyal or playful characteristics, for their attractive
appearance, or for their song. Pets also generally seem to provide
their owners with non-trivial health benefits; keeping pets has
been shown to help relieve stress. There is now a medically-approved
class of "therapy animals," mostly dogs, who are brought
to visit confined humans. Walking a dog can provide both the owner
and the dog with exercise, fresh air, and social interaction.
