Descripción
The aim of this article was to describe the time course of prepubertal sexual steroids in domestic cats. Fourteen newborn kittens were followed up until puberty (physical, behavioral, and hormonal changes). Fecal testosterone [T; males] and E estradiol 17-β [E2; females] concentrations were analyzed by repeated measures ANOVA and two consecutive time windows (TWs) were used to compare changes in both male (postnatal weeks 1–4 vs. 5–14) and females (postnatal weeks 1–5 vs. 6–13). Puberty was achieved 14.3 ± 0.3 and 13.3 ± 0.4 weeks after birth in male and female cats, respectively. In both genders, during TW-1 fecal steroids concentrations were similar (males) or even higher (females) to that previously described for mature cats. Fecal T (P < 0.01) and E2 (P < 0.01) varied throughout the weeks. Differences were found when hormonal concentrations of TW-1 were compared with those of TW-2 both for male (61.4 ± 7.9 vs. 16.9 ± 2.2 ng/g; P < 0.01) and female (78.2 ± 12.5 vs. 11.2 ± 4.0 ng/g; P < 0.01) cats. It is concluded that in domestic cats there is a sexual steroid surge during the first 4 and 5 postnatal weeks in male and female animals, respectively.
