Question about a nature documentary - animals mating

I've seen something in several nature documentaries that confuses me. I'm watching one now about India. It says that a male tiger will kill a young cub from a female tiger if the offspring is not his own. I've seen the same thing on lions and polar bears.

How do they know that the offspring is theirs?

I don't understand? How do you tell which kid is yours? How do you tell which dog at the park is yours?

Grizzly bears do that too.

I assume they check birth certificates? Sorry, I don't know how they tell, or whether they can tell, which cubs are their own.

Seriously?

I can tell which kid is mine because I was there when he was born and all along the way. Male lions, tiger and bears don't stay around to help nurture their offspring.

I think the genesis of the question is addressing risky behavior (unprotected, multiple partners, one night stands, etc) in adolescent mammals, not necessarily between species.

I take my kids to the dog park all the time, even take them off the leash to chase birds...

The answer is scent, a male lion or tiger can tell the difference between his offspring and another cats offspring.

That's apparently something of an open question. As I alluded in my last post, it's not clear that they in fact know the offspring is theirs.

Google found a paper on grizzlies that has some good info:

If you aren't the alpha lion in your territory with your ladies, it's probably not your kid.
