No owners have the same pet, > The question is: "Who owns the fish?" While the clues mention 4 pets: dog, cat, bird, horse, there is nothing to indicate that the 5th 'pet' is actually fish. Thus the answer may be 'noone', the 5th may be a goat. Other than that the problem is either unsolvable (if in fact there is insufficient information) or mechanistic (if there is). I suspect that 98% can't be bothered with it. I also don't believe that Einstein wrote it.
