yodel is driving me nuts with the meowing :)

How much am i supposed to feed this critter?
he jumps on my bed anywhere from 3am to 5am and meows and bumps his nose on
my eyes
until i get up and feed him. But then he does that every time he hears a can
open in the kitchen.

I also think he wants to get outside really bad. I'm not willing to let him
out until i get a a leash and body harness for him
so that is on hold.

But how much am i supposed to feed him?
he's got me up to qty 3 3 oz cans of wet food and has dry food in a small
dish that he mostly ignores.
