Pet sitters work on holidays, weekends, and evenings; it’s not a 9 to 5 gig, but many enjoy the freedom of having a flexible schedule. Some clients may indeed want someone to come check on their furry friends while they are at work, but most will need a caretaker while they are on vacation, which calls for driving to the clients’ homes multiple times.Pet sitters are given a huge responsibility. They are welcomed into another home and are tasked with caring for a family member. As a pet sitter, you must love animals and be willing to become trained at administering medications and first aid if an emergency arises. You will also learn to recognize unusual behaviors, such as a lack of appetite, in order to address problems as soon as possible.
