That statement is inaccurate !

Humans, homo sapiens, have a gestation period of 9 months ! The reccord for one birth period is Octomom !

Now look at the rat productivity and statistics:

Rats multiply so quickly that in 18 months, two rats could have over a million descendants.
One pair of rats has the potential for 15,000 descendants in a year.
A female can produce up to twelve litters of twenty rats a year.
Male and female rats may have sex twenty times a day.
The rat has been called the world’s most destructive mammal - other than man.
Rats destroy an estimated 1/3 of the world’s food supply each year.
25% of all fires of unknown origin are rat-caused.
26% of all electric cable breaks and 18% of all phone cable disruptions are caused by rats

*( Writers note: Male and female rats may have sex 20 times a day but only the female human "putas" that work in bordelos do it as many times. I really don't think the campesino hombres can sustain such a pace - borracho or not ! ).
