• Feeding and providing fresh water for the pets
• Cleaning and changing litter boxes for cats
• Walking and exercising dogs
• Administering medication or special care as needed
• Playing with and providing companionship for the pets

In addition to these tasks, a pet sitter may also be responsible for other household duties such as bringing in the mail, watering plants, and turning lights on and off to give the impression that someone is home. The specific tasks and responsibilities of a pet sitter will depend on the needs of the pets and their owners.
