It is still quite surprising to me that there isn't some web site (if there is I haven't found it!) which shows photos, measurements and comparisons of these species, side by side so you can see the subtle differences. Even a pest control officer said they were mice when we e-mailed him the photos! (Extra point there for my wife!!)
So thanks again everyone, if you manage to find that elusive web site I'd love to know. |
To me the differences are black and white. How good are you scales? These ARE brown rats. Any figure of weaning size in a book is an average, you get larger and smaller individuals in any population which may be the reason for you below average sizes. Also even when they are not fully weaned they will take some solids especially towards the time of weaning.
