The rampant rodent - aptly named Randy - broke into the female pen at the petting zoo in Hatton Country World in Warwick where he lives and remained undetected for four whole weeks.
And we think it's fair to say he had quite a bit of fun during his stay!
Randy was eventually found exhausted from all his action and surrounded by his adoring pregnant conquests!
Despite now being returned to the male enclosure, staff have said the fluffy lothario still had a "twinkle in his eye".
Manager Richard Craddock told The Mirror: "We believe that the newly-named Randy could have impregnated up to 100 female guinea pigs, which have litters of about four, so if you do the maths we could be expecting quite a baby boom."
What a stud!
