- Indoors
- Equipment: Whistle
- Formation: None
The Pack lines up in 4 or 5 lines, each line of Cubs joining hands across. One Cub is chosen as 'Cat' and another as 'Mouse', the 'Cat' chases the 'Mouse' up and down the lines.
When the leader blows the whistle, the Cubs turn at right angles and form lines going down, by holding hands with the members of their new line. When the leader blows the whistle again, the lines form across once more. When the 'Cat' has caught the 'Mouse' a new pair is chosen.
