Pet sitter is nothing more than a crooked company that uses shady sales tactics to sell their services. If you are a pet sitter looking for opportunities, make sure you look elsewhere, and don't even bother signing up for their free service. Once you sign you are a bombarded with emails showing interest in your service. You can reply once a month for free, but after that you will be required to hand over your credit card and upgrade your membership. Once you upgrade your membership you are then able to respond to all your messages (lol)... BUYER BEWARE when you respond to all of those seemingly interested parties, they're no longer interested and don't respond. Pay attention to all of the ads as well, you will see the same ads consistently, even if it's a couple years later. I signed up for a basic account a couple of years back and caught on immediately. If you feel like making a donation go ahead and sign up, but that's about all you are doing!
