In the wild, rats live an average of two to three years, while captive rats generally live three to five years. Find out how wild rats are often killed by predators, while captive rats die of genetic diseases, with information from a science teacher in this free video on rats.

Wild mice are opportunistic omnivores, which means that they eat any plant life or small insects that they come across. Find out how baby mice, like all mammals, start by eating milk from their mothers with information from a science teacher in this free video on mice.

Rats like warm, sheltered places with available food. To get rid of rats, cover up holes that enter a house and avoid leaving any uncovered food near a house. Find out more about discouraging rats with information from a science teacher in this free video on rats.

Mice will eat anything that they come across, including plants, beetles, cereal, cookies and pet food. Find out how mice can chew through almost anything using their large incisor teeth with information from a science teacher in this free video on mice.

Mouse feces looks like small grains of black rice and often has a musty odor associated with it. Plug up holes in your house and cover up food to prevent mice from infesting a house with advice from a science teacher in this free video on mice.

Rats can live in almost any environment, including forests, houses, cold climates and very warm climates. Learn how rats build nests to have babies and keep warm with information from a science teacher in this free video on rats.

While rats and mice are very similar, they do have several differences. Mice tend to be smaller, more rounded and with more fur on the tail and ears than rats. Identify rats and mice with help from a science teacher in this free video on rodents.

Mice are smart enough to be trained to find their way through a maze and find their way into people's houses. Discover how mice are not as smart as dogs, cats, monkeys or dolphins with information from a science teacher in this free video on rats.

Rats and mice are members of the rodent family, which is characterized by continuously growing incisors. Rodents are found on every continent except for Antarctica. Rats and mice particularly have become pests in many areas, due to their ability to eat almost anything and breed rapidly. They can fit in very small spaces and tend to be quite clever. In this free video series on rats and mice, a science teacher explains the basics of these small rodents. Find out how long rats live and what mice eat. Identify mouse feces and learn about what rats dislike. Learn how to tell the difference between rats and mice with the help of these free videos.
