In another lesson, we learned about Earth's four spheres. These are the geosphere, hydrosphere, biosphere and atmosphere. Together, they make up all of the components of our planet, both living and non-living.
All kittens should be born with two anatomical openings just below the tail. One is the anus and the other one is the genital area. The primary way to tell a female kitten from a male kitten is by comparing the distance between the anal opening and the genital opening. Rarely, a kitten may be born without an anus. This is a birth defect and is considered very serious and life threatening.
