PETZ SITTER selects the very best people for our pet sitters. They are insured and bonded along with submitting a Nationwide Database Criminal Background Check through Castlebranch. http://www.castlebranch.com. We also ask they attend an American Red Cross Pet First Aid Class. It is very important to us that you feel extremely confident and comfortable when using PETZ SITTER.
