Study Notes

Feline Mating Behavior

  • A female in heat exhibits specific behaviors, including crouching, rolling, stamping her hind feet, and raising her pelvis.
  • Males detect females in heat through pheromones.
  • During mating, the female bends her tail to one side, allowing the male to bite the back of her neck and insert his penis.
  • The male's penis has spines, which cause the female to emit a "copulation cry" when it is withdrawn.
  • The copulation cry is a distinct vocalization made by the female after mating.
  • Breeding is a repeated process, with multiple matings occurring in a short period.

  • In primigravidae (first-time mothers), mammary development is most pronounced in the last 2-3 weeks of pregnancy in dogs.
  • In multigravidae (mothers who have had previous litters), mammary development occurs in the last few days of pregnancy in dogs and around 7-10 days in cats.

Changes in Pregnancy

  • Teat Development: In primigravida (first-time mothers), teat development begins around day 35 of pregnancy.
  • Multigravidae: In women who have been pregnant before (multigravidae), there is minimal change in teat development.

Physiological and Behavioral Changes

  • Temperament: Women tend to become quieter and more docile during pregnancy.
  • Appetite: Individual variations in appetite are common, but many women experience a decrease in appetite towards the end of pregnancy.

Reproductive Health

  • Vaginal Discharge: A slight, clear, mucoid discharge may be present during the second half of pregnancy.
