Dungeon Petz

Description from the UK Expo:

Described as a game about breeding animals to sell off to evil Dungeon Lords, as all evil lords need a pet! The main principles of the game is the placement workers, which will then allow you to perform various actions (such as getting a new cage for animals, purchase of new baby animals, buying food, cure animals who suffered injuries). Each animal has specific needs which need to be catered for. The larger the animal, the more needs they have and the more difficult is to keep the animal in a cage in a pleasant mood.

Note: This is a stand alone game, NOT an expansion for Dungeon Lords.
