A free program for Android, by Game In Life.

This fun application takes a cute spin on usual line connecting games. Instead of simply linking the ends of two colors, you will have to extend the cat’s body to reach its food. 

When you drag the cat’s face, its tail will be left behind and the body will extend, creating a very colorful line. However, there is a certain path you have to follow to get to the fishes. You will have to pass through each path to finish the level. 

The app is called Hungry Cat and it works on Android phones and tablets. There are plenty of levels and the game is very easy to play.
