Every cat needs some fun and what's a better way to have fun than to dabble with a toy that mimics cats natural prey. This is exactly what German made Trixie does.
 It is handier now than ever before as more and more modern household cats tend to spend their spare time relaxing on the couch. However this is not what a cat was engineering for, hence it is of utmost necessity for the cat to exercise (which this tool provides) to prevent overweight and other similar long term health issues caused by lack of movement.
