Fancy Mouse
Males have musky odor; small & quick
Overview
The Fancy Mouse (Mus musculus) is a small pet, around ~3 in, living 1.5–2.5 years. It is nocturnal — most active at night. Socially it is social (females in groups; males fight).
Is the Fancy Mouse right for you?
A good match if — you're new to small pets; you're around in the evenings, when it's awake; you can house a small group for company.
Think twice if — you want a pet that's lively during the day; you can only keep a single animal — this species needs company.
What a Fancy Mouse needs from you
Day to day it needs a suitable enclosure with very little space, the right diet, daily care and moderate day-to-day upkeep. Crucially, it must be kept with its own kind — keeping a single animal alone is stressful and unfair.
