The cat pack!
Contains 5 agents. Which are all separate agent files so you can choose which ones you want.
The Litter box should only be used with creatures who can handle toxins in their systems.
The scratching post relieves anger, the Sun cozy keeps your creatures warm, the mousie is
 a squeaky toy that rolls around, and the Norn nip is a rather fast growing plant.

Ideas were garnished from suggestions on the DS forums.
