Seems guys with these two types of pets are most likely to cheat. Any guesses? Surprisingly, the answer is bunnies and hamsters. A poll by pet site Moggy or Doggy revealed that 64% of men who have a pet rabbit said they had cheated at least once. 53% of men with hamsters as pets admitted to having at least one affair. 30% of men with dogs admitting to cheating. But it seems guys with no pets at all are the most faithful – with just 29% saying they had cheated on someone. (Best Life)
