How cats are different from dogs

One way cats are different from dogs is that people mostly select which dog breeds with which dog, but cats decide which cats to breed together. This is because dogs do stuff for us, so we care about their characteristics, but all cats have done for us in the thousands of years we have been co-habiting with them is catch vermin, and we have let natural selection continue to operate. Dogs use mostly human selection; cats use mostly natural selection.
