Part-time pet sitting jobs are those in which you care for an animal when its owner is absent, though some pet owners occasionally hire a pet sitter for other tasks as well. In this role, you may walk the pet, feed it, administer medications, and otherwise provide care and support as needed. Hours in this job can be irregular and range from short visits to feed and water a pet during the workday, all the way to staying with the pet for days at a time while their owners are out of town. In this context, part-time work means less than 40 hours per week but could still involve many hours per day. Most pet sitters focus on dogs and cats, but clients may occasionally ask you to sit for unusual pets that have special care requirements.
