I have reviewed several books on the behaviour of cats, and each book has had a unique point of view. Dr. Bruce Fogle sees cat behavior from the standpoint of a veterinarian and biological scientist. As such, he talks about hormones, genetics, the senses, and other biological determiners of the cat's way of interacting with the world. 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.
