It can be stressful for pets when their owners leave. Being able to remain in their own homes can reduce that stress level significantly. Pet sitters fill the void for pets when their human companions are away. In addition to feeding, walking, cleaning cages or litter boxes, pet sitters also provide much needed love and attention while you are away. Pet sitters may also administer medications, perform other pet care duties and home-care services such as watering plants, putting out garbage, providing a security routine, etc.
