Minecraft wiki entry for Beginner%27s_guide, associated text: Neutral mobs act similarly to passive mobs except that they harm the player if provoked. Wolves, polar bears, iron golems, llamas, dolphins, pandas and bees attack the player if the player harms them. These creatures also attack other creatures that hurt them. A polar bear is hostile to the player if a bear cub is nearby, and bees attack if you molest their hive. Bees and wolves both attack as a group: if one of them attacks, all the others in the vicinity join in! For all of these, plus the passive horses, donkeys, and cats, just leave them be for now. They don't drop meat, and you don't have the means to tame or breed them yet.
