A male lion, when taking over a pride, will kill all the young lions that are not his offspring.

I have heard that lions' pack behaviour is more reminiscent of dogs than it is of domesticated cats, which have a more solitary nature similar to tigers or other big cats.

Do you know if this sort of behaviour has also been witnessed in wolf packs?

It's mentioned in Call of the Wild, but that's not a very reliable scientific source.

No; The social structure of Wolf packs is completely different from lion prides. Leadership is shared between a male and female (the alpha couple) who achieve their status independently from each other. Also, the pack includes subordinate males as well as females.

My understanding is that male cats are not necessarily good to have around kittens, even if they are the father, as they may see the kittens as future rivals.

That understanding isn't necessarily based on observed behavior or referenced studies though.

Infanticide is not unheard of in the animal kingdom...
