Found a good helper to make hamster bedding.
1. Tear out 10 pieces of kitchen towel.
2. Layer them one on top of the other.
3. Cut into strips (about 3cm wide).
4. Turn each strip to cut into smaller strips (target: achieve shredded paper thinness).
5. Fluff the pieces (to avoid layer sticking).
6. Crinkle the pieces by squeezing.
