Prepared for current owners, prospective adopters, and anyone fascinated by the charismatic Siberian mouse MSH‑45 “​Masha”.

(All information reflects the most recent research (2022‑2024) on the species Mus musculus sibiricus and the specific MSH‑45 breeding line. If you are unsure about any recommendation, consult a qualified exotic‑pet veterinarian.)

| Time | Activity | |------|----------| | Morning (07:00‑08:00) | Fresh water change; refill food dish (≈2 g/pellet per mouse). | | Mid‑day (12:00‑13:00) | Small treat (e.g., a piece of fresh fruit). | | Evening (18:00‑19:00) | Rotate a “foraging snack” (see Section 5). | | Night (22:00‑23:00) | Quick visual check; ensure wheel runs freely. |

Tip: Keep a logbook (paper or digital) to track feeding amounts, especially if you have multiple mice.

Design principle: Vertical + Horizontal. Masha loves to “fly” up and down; give at least two vertical levels separated by 10‑12 cm.
