Cats are more hostile than dogs. So dogs > cats imo.
Only not really. Dogs are more protective of their pack, and will be more hostile against strangers. A lot of cats couldn't care less, and don't mind being petted by strangers and such. Some cats are more introvert though.
Cats don't mind being petted by strangers? Weird.
