Homer – or whatever oral tradition he was cribbing from when he wrote the Odyssey – didn't always pay attention to details.  This has been a big challenge while trying to write a more "rational' or at least consistent version of the Odyssey.  For example, in the original Odyssey, after they escape the Cicones, the Greeks encounter a six-week storm.  Six weeks?  That's half a season!  On top of that, Greek vessels at the time probably weren't meant for extended sea voyages, but for putting in to shore every night or two.  They wouldn't have carried anything like enough water for fifty men for six weeks.  So I've cut the storm down substantially, and even then, they come close to running out.

An even more interesting example is near the end, with the Cyclops.  Here we have a creature that, in the original, throws a huge rock far enough out to sea to create a huge wave that washes the Greek ship back to shore.  At the same time, it can milk goats.  This would be a lot like us milking mice!

Coming at it from another direction, the Cyclops eats four men in a day.  Assuming them to be 180 lbs apiece, that's 720 lbs of meat (and bone, etc) that the Cyclops eats daily.  If a regular 6′ 180 lb man on an all-meat diet eats about 1.5 lbs of meat a day, that means the Cyclops must be about 480 times the mass of a man.  Assuming he's essentially a really big man, and applying the square-cube law, the Cyclops is about 47 feet tall.

After struggling with this for a while, I removed the whole thing about milking goats that was in the original.  Although I left the cheeses.  Okay, so I'm not totally consistent.  I guess this is just one of the things that you run into when you're stealing from, sorry, adapting ancient sources.  On the other hand, I get a ready-made brilliant plot, so I can't complain.
