Anybody for Dragon Chow?

[Gurthang]

I was just thinking.

Smaug stayed under the mountain for a long time. He didn't come out very often, and he didn't attack the lake-town, or they would have moved away. He just lived under the mountain for a long time.

So how did Smaug stay alive without eating for such a long time? If he did eat, then what? How could he have let himself leave to go find food?

This same question could be asked about many creatures. Such as, how did the Ents get their energy to move? Did the Nazgul need sustainance, and if so, then what? How did Balrogs stay alive?

As far as Smaug goes, I would guess that he basically hybernated. He slept soundly(but with one eye open) for long periods of time and did not use his energy.
