Are Rats and Mice the Same Thing?

Rats and mice are cousins and share a common ancestor. In fact, they are both descendants of anagalids, which were extinct dinosaurs. Without dinosaurs, mammals had more freedom to diverge. The descendants of anagalids are mice, rats, and rabbits.

Despite the similarities, they are different. The term “rat” is generally used to describe both small mammals. Wild rats are robust and healthy; however, those in cities may suffer from poor diets and internal parasites. However, rats are not harmful to humans, and their lifespan is typically two to five years. They are intelligent animals and can be trained to use a litter box, come when called, and perform tricks.

While both mice and rats can damage structures in your home, rats are much stronger and can chew through wires and other materials. They can also contaminate food stored in metal and glass containers. Rats and mice can cause a lot of damage to your home, so finding them early is essential.

Rats and mice share some traits, including size and color. Both are small rodents with long, thin tails. Rats and mice also have similar environments and dietary habits. Rats tend to avoid unfamiliar places, whereas mice are more curious and active.
