Mammary Gland
- Teats are absent.
Female
Reproductive Tract

- Short uterine body
- Single cervix
Puberty and Sexual Maturity
- Sexually mature at 2-4 weeks.
Oestrous Cyclicity
- Oestrus cycle 4-5 days.
- Post-partum oestrus.
- Delayed if lactating.
Gestation and Offspring
- Gestation period 19-21 days.
- Litter size 6-16
- Altricial young
- Eyes open at 12-14 days.
