Is a feline mammal the same as a placental mammal?

Yes and No. Felines are animals closely related to cats (technically excluding the "great cats" ... lions, tigers, etc. ... who are felids but not felines). Placental mammals are those whose gestation includes a placenta (basically, all mammals except the monotremes and marsupials).All felines are placental mammals, but not all placental mammals are felines. Humans, for instance, are also placental mammals.Placental mammals bear live young, (that includes cats) that are nourished in the mother's uterus through the embryonic organ (placenta) attached to the uterus wall. The term "placental mammals" is somewhat misleading because marsupials also have placentae but it is short lived in its part for fetal nourishment. In eutherians, as "placental mammals" are known scientifically depend on the placenta during the full developmental stage of the fetus.
