When you hire a professional pet sitter, make sure you take the time for an interview and have all your questions ready. The services offered and fees charged can vary greatly. You should find out if the pet sitter is bonded, has liability insurance coverage, and is willing to provide references. Ask for documented proof of these and take the time to check references. Also, it will be important to see how the professional interacts with your pet. And, note what information the pet sitter requires from you before taking on the assignment.
