Mice vs rats in research. A mouse conversely may be one tenth the weight of a rat and weighs approximately 1 1 76 ounces 30 50 grams. They have an average body length of about 3 4 inches 7 62 10 16 cm and their tails may be slightly more evenly balanced with their bodies measuring about 3 4 inches.

Rats are omnivorous while mice are especially herbivorous. One easily identifiable anatomical difference is the number of nipples possessed by both species. Droppings different size and shape.
They are readily available easy to handle and very similar to humans physiologically and genetically. Rats have six pairs of nipples while house mice possess five. The animals are often identified.
Biology young mice develop more quickly.
