How to Distinguish a Small Rodent with a Long Nose from a Mouse

Common mice display a compact body ranging from 6 cm to 10 cm in head‑body length, with a tail of comparable length that is typically hair‑less and slightly scaly. The fur is soft, dense, and varies from light brown to gray, often exhibiting a darker dorsal stripe.. Date latest changes:

Rat Chewing Its Cage: Prevention

Rats possess a strong gnawing drive that originates from continuous incisor growth. The instinct to chew serves to wear down teeth, explore surroundings, and alleviate tension. When a cage lacks suitable outlets for this behavior, the animal redirects its activity toward the enclosure itself, resulting in damage.. Date latest changes:
