Deliberate mistake: After Baloo and Bagheera escape from the monkeys, they both have a black eye. However, during their conversation by the water, between shots their black eyes vanish. [This is a Disney tradition, but still a mistake.]
Deliberate mistake: When Baloo lies unconscious, the tree behind has barely no leaves on its branches. When he wakes up and the sun shines, leaves suddenly appear.

Continuity mistake: During the king Louie scene the number of bananas at the feet of his throne increases and decreases randomly between shots. Their position also changes.
Continuity mistake: The branch where Bagheera watches Baloo's boxing lessons is parallel to the ground, but in later shots it's perpendicular, much steeper.
Continuity mistake: When Mowgli finally gets to the man village and the girl drops the water vase, it rolls around and stops in front of him. The camera cuts off it and onto him, and when it cuts back, the vase is in a different spot than before.
Continuity mistake: In the shot where Mowgli says, "But, I want to stay in the jungle," the very right end of his loincloth is miscolored as his skin for a few frames.
Continuity mistake: When Shere Khan chokes Kaa, the snake is two meters away from the tree. In the immediate close-up it is right next to it. (00:58:05)

Continuity mistake: The tree where Bagheera and Mowgli sleep and meet the snake has a small branch protruding which Mowgli fiddles with. The branch appears and disappears randomly between shots.

Continuity mistake: When Bagheera leaves the basket for the wolves to find it, a stone next to it appears close, further away, or simply disappears with no continuity at all.
Answer: The animals considered man a strange creature and did not understand their ways, like wearing clothes and shoes. They were scared when Mowgli brought them fire. They only knew jungle ways, they figured the humans would eat him, like any small creature left on his own. Plus they knew man as a hunter and killer.
