How to interview a pet sitter
Find out if the sitter will be using a vehicle that advertises that your property is empty and will be for a while.
When you are out of town, you do not want to let everyone, especially anyone with criminal intentions, to know that no one is home most of the day. Ideally, there should be no advertisement on the car or truck the sitter drives.
That would be a sure sign that you would be out of town. The security of your home should be a concern of the pet sitter as well as your animals.
