Including the tail? Baaaah, I saw rats that were
21 inches not counting the tail in Vietnam.
Around 72 or 73 a guy came through our town with with an exotic animal display. He had a koala, some snakes, different lizards and such.
The thing I remember best was the Vietnamese rat. That dang thing was AT LEAST two feet long excluding the tail. The tail itself was about a foot long.
I remember my buddy commenting that our troops in Nam were fighting the VC, the NVA and the rodents.
I saw a rat by a dumpster at a 7-11 store once that was as big as that dog!...............
