Prepare

The day before your sitter is to arrive, make sure to print out any email addresses or phone numbers they may need. Include the best numbers to reach you, the number of your veterinarian, and an emergency contact that lives nearby. If you will be staying in a hotel, include its name and phone number in case you cannot be reached on your cellphone. Include clear, detailed instructions on feeding your pets, and how to administer any medications. Dont leave any stone unturned!
Finally, if possible, contact a neighbor you know and trust. Leave them your contact information and the dates you will be away, as well as a spare key in case of emergency. This person can monitor the comings and goings of the sitter and report if there is any suspicious activity.
