I guess not everyone saw “The Lion King”. Those cubs (at least the boys) better enjoy it now. And the following article seems to agree with Hanna (”lions can’t be stepfathers” last paragraph).

Excerpt:
“The lion cubs seem happy and carefree, but their lives are not easy. Only about 1 in 8 male lions survive to adulthood, Dereck said...
But when male lions begin to reach sexual maturity around age 2, the older males within the pride kick them out, Dereck said. The female lions, which are usually all related to some degree, typically stay behind.
For a young male, “the betrayal by his own blood must be confusing to him, but this is an ancient rite — the casting out of young males into a world of unknowns — a world where he will be able make it, or die,” ....
After being kicked out, the young males roam the countryside solo or in small bands, often with their brothers or cousins, negotiating the no-cat’s-land between territories of other lions...A majority of male lions die during this time...
When male lions take over a new territory, they almost always kill the prides’ cubs, since they are not biologically related and do not want to spend energy ensuring that other lions’ genes will be passed on. “They can’t be stepfathers,” Hunter told LiveScience. Female lions also will not be receptive to mating while they are nursing, so killing the cubs enables the male lions to procreate, said Beverly....
Males of many species are kicked out of the herd/pride and surprisingly it’s the females that do it. A female whitetail deer will run off her male offspring as soon as it’s capable of taking care of it’s self.
