How to keep Japanese mice? - briefly
Use a secure, well‑ventilated cage with solid flooring, appropriate bedding, and enrichment items such as tunnels and chew toys; keep temperature around 20‑24 °C and humidity near 50 %. Feed a high‑quality pellet diet supplemented with fresh vegetables, occasional protein sources, and provide constant access to clean water while monitoring for signs of illness.
How to keep Japanese mice? - in detail
Caring for Japanese mice requires a secure, well‑ventilated cage that provides at least 300 cm² of floor space per animal. Wire cages with a solid base prevent escape and allow easy cleaning; glass aquariums are unsuitable because they restrict airflow. Install a solid lid, a chew‑proof barrier, and a lockable latch to protect against predators and accidental opening.
Provide a balanced diet consisting of high‑quality mouse pellets, supplemented with fresh vegetables such as carrot, broccoli, and small amounts of fruit. Avoid sugary treats; limit seeds and nuts to no more than 10 % of daily intake. Fresh water should be offered in a sipper bottle, cleaned and refilled daily to prevent contamination.
Maintain hygiene by spot‑cleaning soiled bedding each day and performing a full cage change weekly. Use absorbent, dust‑free substrate—paper‑based bedding or aspen shavings are preferred. Disinfect cages, water bottles, and feeding dishes with a mild, non‑toxic solution, rinsing thoroughly before reuse.
Enrichment promotes mental health and reduces stress. Include climbing structures, tunnels, and nesting material such as shredded paper. Rotate toys regularly to sustain interest. Handle mice gently, supporting the body and allowing them to explore the hand; short, calm sessions encourage trust and habituation.
Monitor health indicators: steady weight, clear eyes, smooth fur, and active behavior. Observe for signs of respiratory distress, skin lesions, or abnormal droppings. If symptoms appear, isolate the affected mouse and consult a veterinarian experienced with small rodents. Regular health checks and prompt treatment minimize disease spread within the colony.
