A good petsitter will ask you more questions than you ask them. If you decide to go with an agency make sure they are bonded and insured since, ask them for refrences. When we go in for a client interview we have a list of our refrences as well as letters we've recived from clients. Make sure that while they are there for an interview they seem to want to bond with your pets while they are talking to you. A good petsitter will also remember to ask you all the questions that you will forget. You should see our client contracts, we leave almost no questions unasked.
