I believe that he does, its behind the scenes, and even his mother mentioned this as a possibility to which he failed to give a strait answer over rather or not he intened to eat Rin and Kohaku (well of course not Them, but suggesting that others he would.) It only makes sence, since it seems the more powerful a demon is the more he would require in order to sustain his power, and I don't think that power would come from consuming and absorbing the power from other demons.

And if he doesn't then my second choise would be that he'd sooner find it Discusting, because he detests humans and wants nothing to do with them, normaly. I think it would be principle to reject it, if it wasn't necesary.

I think that he used to, and may have stopped after he met Rin. And that makes things sort of ironic, and here's why: I've been looking stuff up. My friend told me that Sesshomaru actually resembles a Chinese woman (in looks and especially clothing), and in myths creatures looking like Chinese women have been known to eat children. Looking like a woman, the children would trust whoever it was, making it easier for them to be devoured. She suggested that maybe the same applied to Sesshomaru, especially since he's not Japanese (he came to Japan from China, for reference watch Swords of an Honorable Ruler).

why would he eat a humen there weak there would be no point in eating one

I don't think he eats human. I think he prefers milk bones. But can't say he never will...

We wouldn't taste delicious enough for him!:D

I think he hunts powerful demons and devours them in his dog form. When he went after the shikon Jewel demon, he referred to him as prey. I believe he bit off the head of one demon in a fight, when he got his arm back. I know Naraku absorbs other demons, but he does wear female Chinese outer wear, so the whole luring children or men is a good possibility. A human here and there would probably be a nice snack for him.

Having read the polls a second ago about fan girls and guys meeting up with him, I had to pick this one. Think about it.

maybe, who knows
