Query: Purr Pals

Purr Pals is the perfect game for the people who aren't fond of the Nintendo dogs DS game. The cats are very realistic, but it is almost impossible to earn money. Also, the cats have endless needs and it takes forever to keep them well fed and happy. Overall, it becomes very repetitive, the cats are the only bonus to the game.
