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.
Approach the cat or kitten with care. In order to determine the sex of a cat or kitten, it's necessary to pick the cat up. Some cats don't like to be handled, so take a little time to let him or her get comfortable around you. Stand or crouch near the cat and let him or her approach you. When the cat comes close, let him or her sniff your hand.
