As a Professional Petsitter in PA, I am not registered with the BBB (I or my husband are the only ones that do the care), nor do I have a criminal background check. You may or may not want to keep those questions in for future inquiries to petsitters. But you can ask if they are "bonded". It is different than a criminal check, but it protects you from theft from the petsitter. I never mind questions from prospective clients, but having SO many questions in an email might have put me off too. A lot of questions are usually answered thru a website (if they have one..many sitters do not) or during a free meet-n-greet. I'm sure you don't want to waste time interviewing sitters and want to "weed" them out, but I would cut down the number of questions (at least in the initial email). Usually just the response from the initial email from them will tell you if they are mature or professional sounding (like if they have a ton of typo's or just the way they address you). Any petsitter should offer a FREE meet-n-greet. A lot of sitters may not want you coming to their house to check our their setup. I don't know...it would make me uncomfortable for some reason, like if my animals act up or coop isn't quite as clean, the client may think I'm neglectful. Although, once someone is a client, I don't mind them coming over at all. I do hope you find someone...but 2 sites you can visit are www.petsitters.org and www.petsit.com. Those are usually professional petsitters and not fly-by-night folks.
