Cat owners speak to their cats, attribute many complex emotions to them and chide them when they bring small dead rodents into the house. People don’t pause to ask what is going on in the mind of the cat during these interactions, and perhaps that’s just as well. The role of a pet is to be relentlessly anthropomorphized.

But for any who may wonder what their feline companions are really thinking, “Cat Sense,” by John Bradshaw, provides the best answers that science can give for the time being.

Dr. Bradshaw, a biologist at the University of Bristol in England, has studied animal behavior and cats in particular for the last 30 years. The starting point of his analysis is that cats are still essentially wild animals. They wandered into our encampments when we first started to store harvested grains, which attracted mice.

Unlike dogs, which have been greatly changed by domestication from their wolf ancestor, cats have almost never been bred for a purpose. They caught mice well enough, and their kittens made attractive companions. So cats have stayed much the same, with any evolutionary trend toward domestication constrained by frequent interbreeding with wild cats.
