some fighting amongst animals in some episodes, usually in self defense, but sometimes out of disagreements or establishing hierarchy. some death occasionally results. there is sometimes blood.
also there are also a few rare human/animal confrontations.
Mowgli is attacked by a jackal in one episode.
Mowgli and other wolves sometimes hunt deer, rabbits, cows and other prey in some episodes.
in one episode it is implied that humans are killing animals, this greatly upsets Mowgli.
Mowgli's wolf father Alexander fights against Shere Khan in an early episode. it is implied that he was defeated in the fight.
in one episode Mowgli attacks Bagheera because he feels rejected by the animals and thinks that being human makes him evil, but the fight does not last long because Mowgli's mother Luri breaks it up and forces Mowgli to apologize. Bagheera is shown with minor scratches and bite marks.
Shere Khan fights against Mowgli in one episode, Mowgli slashes Shere Khan's eye, blinding him in that eye.
the second and final fight with Shere Khan is more intense, Mowgli fights him with a burning stick, burning him a few times. Shere Khan tries to climb up a cliff, but he falls back down. Mowgli then finishes Shere Khan by jumping into the air and stabbing his chest with a knife.
in later episodes we then see Shere Khan's gutted hide.
Mowgli occasionally falls out of trees or runs into things.
