The German keeps fish.

## Reasoning

Number the houses from left to right. We have the following information:

 Clue 1 2 3 5 6 7 8 9 11 13 14 House 3 1 2 Colour red green yellow blue Nationality English Swede Dane Norwegian German Cigar Pall Mall Dunhill Blue Master Prince Drink tea coffee milk beer Pet dogs birds

The green house is not number 2, which is blue. Consequently and from clue 4, it is not 1 or 5. The green house resident drinks coffee, therefore the house is not 3 (whose resident drinks milk). Therefore the green house is 4, and the white house is 5.

This leaves determining the colours of houses 1 and 3. The red house is not number 1 (residents are English and Norwegian respectively) so 3, and house 1 is yellow.

 House 1 2 3 4 5 Colour yellow blue red green white Nationality Norwegian English Swede Dane German Cigar Dunhill Pall Mall Blue Master Prince Drink milk coffee tea beer Pet dogs birds

From clue 12, horses are kept in the grounds of house 2. The Norwegian doesn't drink tea (the Dane does) or beer (the Blue Master smoker does) so water. Hence from clue 15, the Blend smoker lives in house 2. We now have:

 House 1 2 3 4 5 Colour yellow blue red green white Nationality Norwegian English Swede Dane German Cigar Dunhill Blend Pall Mall Blue Master Prince Drink water milk coffee tea beer Pet horses dogs birds

from which most of the information easily falls into place:

 House 1 2 3 4 5 Colour yellow blue red green white Nationality Norwegian Dane English German Swede Cigar Dunhill Blend Pall Mall Prince Blue Master Drink water tea milk coffee beer Pet horses birds dogs

Finally, clue 10 tells us that the Norwegian keeps cats, and the German keeps fish.
