About rodents in general
Rodents are mammals, which are characterised by a single pair of continuously growing incisors (front teeth). They are the most diversified mammalian order and live in various terrestrial habitats, including human-made environments.
Rats and mice are rodents that can transmit various diseases to humans such as leptospirosis, murine typhus, rat bite fever, plague, etc. They are highly ferocious, adaptable to changing environments, and have a high reproductive rate.
However, they have poor visual acuity and colour blind, relying on their extremely strong senses of hearing, touch, taste, and smell. They are active climbers, excellent jumpers, and swimmers.
