What does this quote from A Tale of Two Cities mean?

Question

...judiciously show a cat milk, if you wish her to thirst for it. Judiciously show a dog his natural prey, if you wish him to bring it down one day.

Answer 1

Could you tell us specifically what you don't understand? Like, say, if it's a word thing or an interpretation thing?

Answer 2

Hmmm...... It means that if you want someone to do something, you need to tempt and direct them in a manipulative way. That's how I understood it, but I may be wrong.

P.S. Great book choice, it's one of my favourites.
