Who Owns the Zebra?

On a city block there are five houses in a row, numbered from left to right, each of a different color and inhabited by men of different nationalities, with different pets, drinks and cigarettes. You are given the following clues:

• The Englishman lives in the red house;
• The Spaniard owns the dog;
• Coffee is drunk in the green house;
• The Ukrainian drinks tea;
• The green house is immediately to the right of the ivory house;
• The Old Gold smoker owns snails;
• Kools are smoked in the yellow house;
• Milk is drunk in house #3;
• The Norwegian lives in house #1;
• The man who smokes Chesterfields lives in the house next to the man with the fox;
• Kools are smoked in the house next to the house where the horse is kept;
• The Lucky Strike smoker drinks orange juice;
• The Japanese smokes Parliaments;
• The Norwegian lives next to the blue house;

Now, who drinks water? And who owns the zebra?

I remember reading this puzzle in the International Edition of Life Magazine, back in 1962.

I give up, show me the solution.
