The duties of a pet house sitter focus on caring for a client’s home and their pets while they are away. During a house sitting job, you care for the animals in the house in addition to the property. Your responsibilities usually include taking the pets for a walk. You also clean, feed, and care for the animals. You live in the house full time and stay there overnight. Depending on the agreement with the homeowner, you may also perform maintenance tasks, get the mail, cut the lawn, and care for gardens. Your job typically lasts for the duration of the owner's vacation.
