Approximately 96 percent of cats still choose their own mates these days. This has made for a relatively unaltered and organic genetic through line in the majority of our modern cats. But that doesn’t mean cats haven’t changed simply by living with us. In a sense, cats have self-selected: friendlier cats, who are more tolerant of humans, may be more likely to be fed and sheltered by them, and more likely to mate with cats who have similar friendly/tolerant genes.
