====Pregnancy diagnosis====
*Foetuses may be palpated by gentle abdominal palpation as early as 10 days post breeding. They can be felt as 1 to 1.5cm masses in the caudal ventral abdomen.
*At 18 days they become 2.5 to 3cm in length.
*Radiography or ultrasonography can be used after 21 days if necessary.

==Sexing==
Kits are best sexed at birth or at weaning (5-8 weeks of age). In between those times it can be difficult to exteriorise the genitalia.
Sexing is performed by gentle pressure on the genital orifice which everts the penis or vulva. The male has a cylindrical organ with a rounded to oval-shaped urethral opening. The female vulva has a leaf-like appearance with a slit-like opening.
In the male the testicles descend at around 12-14 weeks of age and can be palpated, although they can be retracted into the abdomen if the rabbit is stressed.
