Anyone who’s ever had a run-in with a NYC rat knows they share virtually no commonality with an ordinary mouse other than four feet and a tail. I’ve seen some that approach the size of gophers. They’re formidable and the city has found them almost impossible to exterminate. No wonder the feral cats of the city have had little success. If you’d like to know more, this book will fascinate. Their ability to fit those fierce bodies thru a hole of almost any size is downright frightening. This is a book that I remember examples from whenever the topic arises. You will too.
