You can contact a pet sitter using the green contact button on their profile. You will need to enter the dates, type of service and some basic information about your pet (the more, the better!) on the contact form so the sitter can get a good idea of what you need.
Please note that the profiles do not include any contact details that will let you contact the pet sitter directly, such as phone numbers or email addresses. This is a conscious choice, as we wish to protect the privacy of the pet sitter by not publicly displaying those details. They get to decide which contact details they pass on to you via private message, once they have accepted your request.
