Why the tiger almost killed Roy.

I'm curious about where you found the info on how they know the male
knows if the offspring is his? It assumes that the female's territory
is completely contained in the territory of one male; an assertion I
didn't run across. Just curious.

Sorry, I missed your post, only saw it today. I believe I have this in
one of my "Wild Africa" videos and I´ve also seen it in Discovery
Channel. Yes, the females´ territories are completely contained within
the male´s territory. Male territories are many times larger than the
territory of females. One curious thing that I have seen in Discovery
is how two or three male cheetahs will team up to protect territory,
hunt, and reproduce. They share the females without any fighting.
There´s a tom in my neighborhood and my house belongs to his
territory. Sometimes at night I can hear him fight in the distance so
my guess is he´s defending his area. A feral female appeared here with
kittens at the end of last year and this tom has not once showed any
agressiveness towards these kittens even now that they are grown. I
have no doubt this tom is their father. One very interesting thing
that I noticed about this tom is that he will *not* allow the females
to wonder out of my property while he allows the males to follow him.
I wonder if he would behave in the same way towards the males if I
hadn´t neutered them. Maybe he would. Maybe that´s a feline father
teaching his young how to fight and defend territory to pass on his
genes.
