Catz review. Classic Game Room presents a CGR Undertow review of the European version of Catz for the Nintendo DS developed and published by Ubisoft. Catz is a pet simulator in which players care for an adorable pet kitten. Feed them, play with them, brush them and watch them sleep. Hey, you take what you can get with cats. And Catz, for that matter. Ubisoft's Nintendogs alternatives on the DS were never very well-received by critics, and for good reason. But for younger, less discerning players, Catz isn't the worst option on the Nintendo DS. Earn money by doing tasks for friends and neighbors, and use that money to buy new toys, clothes and food for your kitten. This video review features video gameplay footage of the European version of Catz for the Nintendo DS and audio commentary from Classic Game Room's Derek.
