I also have a background in the biological sciences, and I found myself frequently nodding in agreement to Dr. Fogle. Cats tolerate both heat and cold better than humans. Cats can learn from watching other cats, but they learn best from their mothers. The pupils of a cat's eyes respond as much to emotion as they do to light. The pupils grow larger and rounder when the cat is emotionally excited.
Cats cools their bodies through grooming.
A cat will groom more in hot weather than in cold weather. It is thought that cats domesticated themselves. They saw a good place to live among humans, and moved in. When a population of cats becomes crowded, the cats alter their behavior and become more like lions. The females share care of the kittens, nursing all the babies in the group.
