What began as a routine day at an animal park in Warwickshire, England, turned into one of the strangest population surprises its staff had ever encountered.
At Hatton Country World, keepers suddenly discovered that something was very unusual among the park's guinea pigs. The females, which were normally kept safely separated from the males, were becoming pregnant one after another.
At first, there was no obvious explanation.
The park had deliberately separated its male and female guinea pigs, so an unexpected wave of pregnancies should not have been possible. Yet staff were faced with the remarkable possibility that as many as 100 female guinea pigs were pregnant at roughly the same time.
Then they found the culprit.
His name was eventually changed to Randy, a two-year-old male guinea pig who had somehow managed to get out of the male enclosure and into the female-only area. By the time staff discovered him, he appeared to have been living in the enclosure for long enough to make a very significant contribution to the park's guinea pig population.
The resulting story became an unusual example of how quickly a seemingly minor escape can turn into a major animal-management problem.
The Mystery of the Pregnant Guinea Pigs
The story took place at Hatton Country World in Warwickshire, where the animal park already had a substantial guinea pig population.
According to contemporary reporting by ITV News, the park had around 300 guinea pigs in total when staff realized something unexpected was happening. The males and females were normally kept in separate enclosures specifically to prevent uncontrolled breeding.
That separation made the discovery particularly confusing.
Staff began noticing that the female guinea pigs were pregnant despite the fact that the male animals were supposed to be nowhere near them.
There was no obvious explanation.
Had one of the animals somehow escaped? Had an enclosure been left open? Had someone accidentally moved an animal into the wrong area?
The answer eventually turned out to be much simpler—and much more surprising.
There was, in fact, a male guinea pig inside the female enclosure.
And he had apparently been there for quite some time.
Enter Randy
The male guinea pig was about two years old, and after his discovery, staff gave him the fitting nickname Randy.
The name quickly became attached to the unusual story because the animal had apparently managed to spend weeks inside the female enclosure without being noticed.
When staff finally found him, he was reportedly taking a nap in the straw.
There was another clue that helped explain what had happened: Randy appeared to have lost some weight.
According to ITV News, staff had already commented that he looked somewhat thinner than before. They only understood the possible reason after discovering him among the females.
The park's manager, Richard Craddock, explained at the time that staff did not know exactly how Randy had managed to enter the enclosure.
There were several possibilities.
One possibility was that somebody had accidentally returned him to the wrong enclosure after handling him. Another was that Randy had somehow escaped from the male enclosure himself and found his way into the female area.
Whatever the explanation, once Randy had reached the females, the consequences became obvious.
The park suddenly had a very large number of expected guinea pig babies on its hands.
One Male, One Hundred Females
The most astonishing part of the story was the estimated scale of Randy's unexpected adventure.
Park staff believed that Randy could have mated with as many as 100 female guinea pigs.
If each female subsequently produced an average-sized litter, the park estimated that approximately 400 babies could eventually arrive. Contemporary reports from ITV News and UPI both described the expected population increase as roughly 400 guinea pigs.
