You may never see a mouse or rat unless an infestation is severe.
Rodents are commonly used in animal testing , particularly mice and rats , but also guinea pigs , hamsters , gerbils and others. Mice are the most commonly used vertebrate species, due to their availability, size, low cost, ease of handling, and fast reproduction rate. In the UK in , there were 3. The most common species used were mice 3.
Although there are more than 20 types of rodents in British Columbia, only 3 cause common domestic or farmyard problems. This includes the:. Rats and mice can cause significant property damage because they chew or gnaw on building insulation, siding, wallboard and wires. They eat a variety of foods, including food you might have stored in your cupboards or pantry. If you eat food that has been contaminated by rodents, your may get a foodborne illness.
Here we provide general information on the housing and husbandry requirements of commonly used laboratory rodents, including mice, rats, guinea pigs, gerbils and hamsters. The laboratory mouse is derived from the wild house mouse Mus musculus , a largely nocturnal burrowing and climbing animal which builds nests for regulation of the microenvironment, shelter and reproduction. Mice do not readily cross open spaces, preferring to remain close to walls or other structures. A wide range of social organisations has been observed depending on population density, and intense territoriality may be seen in reproductively active males. Pregnant and lactating females may aggressivley defend their nests.
Rats are various medium-sized, long-tailed rodents. Species of rats are found throughout the order Rodentia, but stereotypical rats are found in the genus Rattus. Other rat genera include Neotoma pack rats , Bandicota bandicoot rats and Dipodomys kangaroo rats. Rats are typically distinguished from mice by their size. Generally, when someone discovers a large muroid rodent, its common name includes the term rat , while if it is smaller, its name includes the term mouse.
The study: Ben Vermaercke and his colleagues at KU Leuven gave two cognitive-learning tasks to lab rats and students. In the first task, the patterns varied […]. In the first task, the patterns varied on only one dimension—either orientation or spacing—and rats and humans performed it equally well. In the second, the patterns varied on both dimensions, and the rats did better than the humans. Interview by Alison Beard.
This chapter provides an overview of the natural history, anatomy, physiology, clinical examination, common diseases, and treatment of rats Rattus norvegicus and mice Mus musculus in the context of veterinary medicine. Guidelines for the care and feeding of rats and mice can provide owners with information to help prevent disease in their pets. Useful techniques for restraint, clinical examination, and diagnostic sample collection are provided to aid veterinarians in thorough evaluation of these small rodents. Common diseases and treatments are discussed separately for each species, organized by organ system. Zoonotic diseases are also discussed to provide guidance for rat and mouse pet owners. Although the medical approach to the many small rodents species commonly kept as pets is similar, unusual species are sometimes encountered in practice, and more specific information about these species can be found elsewhere. The mouse belongs to the family Muridae, subfamily Murinae.
