How do I get hats for my pet?

Your pet can wear a hat, or none: 12 to start working toward, and secret hats you find along the way (see the question about secret items). Tap your pet's card on Home anywhere except on your pet, pick the Hat tab, and tap a hat; it's saved right away, and your pet wears it on Home, in its details, in shared pictures, and in the Home Screen widget (iPhone and iPad). The 12 open up with your streak like room items, on their own numbers: the first three come quickly, at 3, 5, and 9 kept planned days (or in your first month for publishers), and the rest take longer, up to 120 days (or 12 months). If you turned off Show streak, or you log hours but haven't made any plans, the first three open up in your first active month and the rest one month at a time. A locked hat shows the number or month it opens up at, and once a hat opens up it stays open. Your pet takes its hat off while it rolls over or lies down. Your buddies see your pet without its hat.
