In cat and mouse tail a cat (or a picture of your own cat!) has to catch as many mice as possible. Each mouse you catch, will walk behind you. You are not allowed to touch the borders or yourself including the caught mice.

There are 30 different levels. If you catch enough mice, the next level will be unlocked. Every next level, the field will be larger and the cat will move faster.
You can also battle against another cat. Try to catch the mice before your opponent does. Try to surround your opponent. He will release some mice that way!
In the hardest level you play against another cat, but there are also some obstacles in the way that you cannot touch!
