Actually it's the opposite! Male cats may kill the offspring of other male cats as this brings the female into oestrus again & ready for mating. The same applies to lions. It is because each individual animal's genes are programmed for reproduction in the best way possible ~ not necessarily for the survival of the species as such, but for that particular animal's survival & ability to pass on its own genetic material.
Adult male cats have nothing to do with the rearing of young ~ once they've mated, their job is done & it's up to the females to rear the young & teach them how to survive as adult cats. So there are no "paternal" feelings in male cats. However related male cats can form brotherhoods to defend a territory & its population of female cats ~ similar to lions.
Entire male cats may well look out for pregnant & kittening females but only to find females capable of breeding ~ then they can kill the kittens & mate with the female themselves.
Most of our pet cats are now neutered so the behaviour of most male cats we see is very different from unneutered males. This could explain why some, more sociable neutered males are prepared to be friendly towards kittens & young cats. Their drive to breed is no longer there & likewise the drive to kill other kittens will also be gone.
