A guinea pig called Randy fathered 100 newborns after breaking into a female pen undetected for four weeks.
A further 80 births are expected at the petting zoo after Randy was found exhausted and surrounded by his pregnant conquests.
He is back in the male enclosure but still has a "twinkle in his eye" after his sexploits at Hatton Country World, near Warwick.
Keeper Jess Middup, 18, said: "He's recovered from his exertions but we'll keep an eye on him in case he makes a bid for freedom."
Manager Richard Craddock said: "One of our male guinea pigs managed to find his way into the female enclosure and had a very good time by the looks of it.
"We suspect a child may have placed him back in the wrong pen by accident after stroking him or Randy may have somehow broken out of his enclosure to get to the females."
"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.
