Como dizer "O olho do dono é que engorda o gado" em inglês

And also "fattens the horse"...
To the ones that don´t raise cattle!

Aqui o tal do "related".

Por quê o gado (ou a tropa) não engorda, PPaulo?

- When the cat's away, the mice will play.
When no one in authority is present, the subordinates can do as they please.

(thefreedictionary)

Makes a whale of a sense, not

I learned also that in Polish they say "the master´s eye makes the horse fat" and in French "the eye of the master fattens the steed."

In fact everyone claims credit for this proverb, he hee, I also found these ones (from "English proverbs" on Google Books):
No eye like the master´s eye.


The eye of a master does more work than both of his hands. (a bit like the "cat´s away" stuff)
