Small rodents are a diverse group of mammals that typically have small bodies, short limbs, and long tails. Common examples include mice, rats, hamsters, and gerbils. They are known for their continuously growing front teeth, which they need to gnaw on various materials to keep them from becoming too long. Small rodents are found in many habitats around the world, from forests to urban areas. These animals are often kept as pets due to their manageable size and relatively simple care requirements. Small rodents are generally social creatures, enjoying interaction with their own kind and sometimes with humans. They play an important role in ecosystems, serving as prey for larger animals and helping to disperse seeds.
