[LM_NET] ELEM: need book title -- rats in NY and overpopulation?

[Suzanne Ng <sng@SOMSD.K12.NJ.US>]

Grade 3 teacher remembers a book she may have seen at a workshop a few years back, 
about rats in NY and how they breed quickly.. i.e. mother rat has babies and within 
a few weeks(?), she can reproduce again, and the rat babies can begin having their 
own babies. 
 
 She says it doesn't have many words, so it is probably a picture book. She'd like 
to use it soon with her population unit in social studies. 
 
I've checked my online catalog, looked at the books with keyword "rats" but nothing 
seemed to fit her description. 
Anyone know this book ? Thanks!
