feline estrous cycle

  • Proestrus -> estrus -> diestrus -> anestrus

    • Proestrus: <1 day and associated with presence of ovarian follicles increasing circulating estrogens

    • Estrus: peak estradiol and male mounting/coitus

      • Behaviors: vocalization, lordosis, rolling, rubbing, foot treading

      • MULTIPLE INTROMISSION: often over several days and are necessary to release GnRH and subsequent LH -> cascade causes final follicular and oocyte maturation and result in ovulation after mating

  • Diestrus: 1+ CL produce progesterone that stays elevated regardless of conception or not

  • Anestrus: circulating estrogens at nadir
