AbstractThis research consists of study of shematic macroscopy cat's placenta and placental characterization as its type, zonary placenta, that 62,5% of cases presents a fissure at distal area of umbilical cord. This is formed by a joustfetal area, joustplacental area and middle area, histological findings: two arteries, a vein, two vitelline pedicule and two allantois pedicule. In the fissure, an allantoic epithelium covering this area at 10% of the cases and 90% found a trophoblast decrease compared with others placental areas out of the fissure. So, the feline placenta, in its maternal/fetal relationship shows a imcomplete zonary placenta, different of that occurs in other carnivores.
