Any of the relatively small placental mammals that constitute the order Rodentia, having constantly growing incisor teeth specialized for gnawing.

Wikipedia

Rodents are a group of mammals. They form the order Rodentia (row-den-she-a).

They have four incisors that keep growing, and must be kept worn down by gnawing (eroding teeth by grinding them on something hard); this is the origin of the name, from the Latin "rodere", "to gnaw", and "dent", "tooth".

Most rodents are small. Examples of commonly known rodents are mice, rats, chipmunks, and squirrels. Some other small rodents sometimes kept as pets are Guinea pigs, hamsters, and gerbils.

Examples of larger rodents are porcupines, beavers, and the largest living rodent, the capybara, which can grow to between 105 and 135 cm (40-55 in) in length, and weigh 35 to 65 kg (75-140 lbs).

Almost half of all mammal species are rodents. More examples of rodents are voles, prairie dogs, groundhogs, and chinchillas.

Rabbits, hares, and pikas are sometimes called rodents, because they also have teeth that keep growing. But in 1912 biologists decided to put them in a new, separate order, Lagomorpha, because they have two extra incisors in their upper jaw.

Shrews are sometimes called rodents, because they look like mice, but that is not correct. They are in the order Insectivora.
