Cuckoo cats can usually sexed by what is called venting. Altho the males are usually a little bit smaller and have slightly longer pectoral spines.
Females have a round papilla, where as the male have a pointed papilla that is approximately 3-5 mm, and gives the appearance of slightly triangular in shape.
