Mouse vs rat
The 2 most famous (or infamous) rodents can be easily distinguished by 3 things: their size, tail, and ears. Mice are diminutive, even compared to young rats; they have thin long tails covered with fur while rats’ tails are thick and hairless. Mice have ears that are bigger in proportion to their bodies and are round and floppy with a tiny, triangular face. Rats’ faces are more prominent and blunt.
