On Chicken Smoothie, there are Unreleased pets (UR pets.) They are considered some of the most wanted pets on CS, therefore they are very rare and valuable. They were first released on 18 December '08 with a very rare chance of adopting one. The URs were available to adopt at a small chance again on 18 December '09. Since then, on December 18th, random pets from any earlier year have been released alongside the UR's. Unreleased Pets are still harder to get-- they are more rare.
