Question: what is the difference between mouse rat and rodent?
Answer: Mice are not only shorter than rats, they also, logically, weigh less. Mice weigh 30 to 90 grams while rats are between 350 to 650 grams. If you see a rodent that looks like it needs to cut back on the sweets, you are probably looking at a rat, as they tend to look fatter than mice.
