Reproduction
Unlike their cousins, the Allegheny woodrat are not a prolific breeders. The breeding season is variable across their range, but is broadly between March and October, and they average two or three litters per year. Gestation lasts 30 to 36 days, and results in the birth of a litter of one to four young (typically two)
The young are born hairless and blind, weighing 15 to 17 grams (0.5 to 0.6 oz). They become fully furred at two weeks, and open their eyes at three weeks. They live with their mother in a nest composed of grass, bark, and similar materials, often located in relatively inaccessible crevices or ledges.
Allegheny woodrats become sexually mature at three to four months of age, and, in the wild, have been known to live up to 58 months.
