Key Differences
Mice are smaller in size, typically weighing 30 grams and possessing delicate features, making them less noticeable in human dwellings. Whereas rats are significantly larger, with some species like the brown rat weighing over 500 grams, making their presence more conspicuous.
Mice have a higher reproductive rate, with females capable of producing a large number of offspring annually, which allows their populations to increase rapidly under suitable conditions. On the other hand, rats also reproduce quickly, but their larger size means they require more resources to sustain their populations.
Mice are known for their timid nature, often avoiding human contact and preferring to hide when threatened. Rats, in contrast, can exhibit more aggressive behavior, especially when cornered or defending their territory, showing a bolder approach to threats.
When it comes to diet, mice are primarily omnivorous but tend to consume more plant material, grains, and seeds. Rats are less picky, with a diet that includes a wider range of food, from trash to meat, demonstrating their adaptability to different environments.
In terms of habitat, mice are more adaptable to indoor environments, making their nests in hidden areas within buildings. Rats, while also capable of living indoors, often thrive in a variety of outdoor environments as well, from fields to urban sewer systems.
