Step-by-step explanation:
Rats have three surprising things in their burrows that are typically found only in the human world:

- Horizontal, curved, and rope-like burrows that can occasionally cross each other.
- The ability to store and hoard food in their burrows, similar to how humans store food in pantries or shelves.
