mouse and rat
Young, weaned rats are still larger than adult mice, weighing around 100 grams at six weeks. However, to the casual observer, very young rats and adult mice can be difficult to tell apart.
Here's what to look for: baby rats will have more juvenile proportions than adult rodents. Their heads and feet will be large relative to their bodies, their faces will be stubby and blunt with wide noses. Adult mice, on the other hand, will have adult proportions: a small, triangular head with a small nose and little delicate feet as compared to the body. In addition, mouse ears are very large relative to their heads, rat ears are smaller relative to their heads. Rats also have thicker tails than mice.
