The Goal is shining
Try to get your reward from the fridge without getting caught by the Cats. You can see the cheese so clearly that not even a hundred Cats can stop you from getting it!
Run, little Mouse, Run!
You are small, and the House is so big. But you can be very fast. Run as fast as you can and hide when it's needed. Just don't stop on your epic quest and claim the best reward ever.
Use your brain
Explore the surroundings to find every possibility to set the cats up and get rid of all of them. Throw, break, chew through, or do whatever you want. It's all for a final great purpose.
Clean the House
Let people do the dirty work and remove the Cats from the House. No Cats are needed in this beautiful place. This is their true destiny. Nothing personal. It's just business.
