I think it's easy to get confused because cat owners will often go straight into petting a cat's head from above, but those relationships have been built over a long period of time (maybe since the cat was very young) and definitely aren't how you should approach an animal for the first time.When you want to pet a cat first move your hand from below so they can get a sniff, you will either get permission or a bite, so you know if you are approved or not.
