Read the FAQ section below and if that doesn't get your question answered, you can reach out via the following:
Q: What kind of iPad do I need?
A: We support any iPad that can run iOS 6 or better. Apple states, 'iOS 6 is not available for the iPhone 3G or earlier, iPod touch (3rd generation) or earlier, and iPad (1st generation)’.
Q: I bought a Squirrel breed or map, and I didn't want to. How do I get a refund?
A: No problem. We still like you. You can request a refund directly from Apple via this link. Follow the directions and when the form appears, select "Problem not listed here". In the text entry just put, "Would like a refund." Apple should respond in a few days. The map or breed will remain installed in your copy of the game until you delete the app.
Q: Tell me more about Apple's In-App Purchase system.
A: Sure. This link has all kinds of information.
