Cat Pong! pretty kitty puzzle

A cat is traced, linked and put out. Prettily, a very refreshing puzzle game appeared. The operation is easy, but the game is deep. When a cat is eating fish, the mouse which snatches fish appears. I'll link more than 3 cats and get rid of a mouse. When I get rid of 10 mice, it'll be a fever mode. Chance of a high score! When a lot of cats are linked and put out, remaining time is extended. You can play as much as you like at time I like anytime. You can be healed and train a brain, and it's the game which can kill time!
