🏠Housing a Fancy mouse: 60 × 40 cm and the full setup
Fancy mouse : A tank or cage of at least 60 x 40 cm with bars spaced under 6 mm, furnished vertically. Hemp or paper bedding and a cosy nest of shreddable material.
In short: Around 7 to 10 cm without the tail and 25 to 45 g, a lifespan of 1.5 to 2.5 years, and a curious, busy temperament. Lively and a tireless explorer, it climbs endlessly and must be handled with care. Females thrive in small groups while males fight: its tiny size demands very narrow bar spacing or a tank.
60 × 40 cm of floor: the serious minimum
For a Fancy mouse (and it does not live alone), aim for 60 × 40 cm of uninterrupted floor space — shop cages almost always fall short. Then add height: solid levels, ladders and hammocks multiply this climber’s territory.
The standard layout
Dust-free bedding 5 to 10 cm deep, one hideout per animal plus one, a nest of hay or ink-free paper (never fluffy cotton, which garrottes limbs), a ceramic bowl and a bottle checked daily.
Temperature and placement
A temperate room (18 to 24°C), no direct sun or draughts, away from speakers and the television. And definitely not a bedroom: the Fancy mouse lives by night, wheel and digging included.
