The objective of this article was to biologically validate in domestic felids the "field method" for progesterone (P4) fecal extraction by a correlating fecal and serum values. Additionally, fecal P 4 concentrations in different stages of estrous cycle were compared. A total at of 16 fecal samples from 13 postpubertal female cats were used. The samples were collected during estrus (n=3), luteal phase (n=10), and gestation (n=3) defined by behavior, vaginal cytology or ultrasonography. Simultaneously blood samples were drawn (n=12). The "field extraction method" was carried out in fecal samples and then P4 was determined by radiommunoassay in all the cases. Fecal P4 concentration ranged from 20 to 463 ng/g wet weight. Pearson correlation coe...
