I'm not sure if it's a good idea to allow children to be hooked on games that involve money.
All games involve money... And these kitties are more like collectibles anyway. Trading and breeding them in virtual currencies also more likely helps kids learn to use money. They will also get to learn about genetics and how it works while they are at it.
I'm not all that worried about them getting "hooked" on this game. In fact I kind of doubt it. Any collectibles will lose their appeal in time. (At least for me they did.)

Not all games involve money. But you know the game and your kids better than I do.
