Lifespan, ageing, and relevant traits

Maximum longevityNot yet established
Observations

Most females do not breed before they are 2 years old and if they do, their litters will be smaller than average. Little is known about the longevity of these animals. In the wild, they can live up to 4 years [0434]. Anecdotal reports suggest they can live up to 6 years, but these have not been confirmed.
