The brown rat, also known as the common rat, street rat, sewer rat, wharf rat, Hanover rat, Norway rat and Norwegian rat, is a widespread species of common rat. One of the largest muroids, it is a brown or grey rodent with a body length of up to 28 cm (11 in) long, and a tail slightly shorter than that. It weighs between 140 and 500 g. Thought to have originated in northern China and neighbouring areas, this rodent has now spread to all continents except Antarctica, and is the dominant rat in Europe and much of North America. With rare exceptions, the brown rat lives wherever humans live, particularly in urban areas.
The fancy rat is the domesticated form of Rattus norvegicus, the brown rat, and the most common species of rat kept as a pet. The name fancy rat derives from the use of the adjective fancy for a hobby, also seen in "animal fancy", a hobby involving the appreciation, promotion, or breeding of pet or domestic animals. The offspring of wild-caught specimens, having become docile after having been bred for many generations, fall under the fancy type.
Terrier is a type of dog originally bred to hunt vermin. A terrier is a dog of any one of many breeds or landraces of the terrier type, which are typically small, wiry, game, and fearless. There are five different groups of terrier, with each group having different shapes and sizes.
A rat-catcher is a person who kills or captures rats as a professional form of pest control. Keeping the rat population under control was practiced in Europe to prevent the spread of diseases, most notoriously the Black Death, and to prevent damage to food supplies. In modern developed countries, such a professional is otherwise known as a pest control operative or pest exterminator.
The domestication of small mammals to keep as pets is a relatively recent development, arising only after large-scale industrialization. Historically, Western society was more agrarian than today, with rodents as a whole seen as vermin that were carriers for disease and a threat to crops. Animals that hunted such pests, such as terriers and cats, were prized.
The domesticated silver fox is a form of the silver fox that has been to some extent domesticated under laboratory conditions. The silver fox is a melanistic form of the wild red fox. Domesticated silver foxes are the result of an experiment designed to demonstrate the power of selective breeding to transform species, as described by Charles Darwin in On the Origin of Species. The experiment at the Institute of Cytology and Genetics in Novosibirsk, Russia explored whether selection for behaviour rather than morphology may have been the process that had produced dogs from wolves, by recording the changes in foxes when in each generation only the most tame foxes were allowed to breed. Many of the descendant foxes became both tamer and more dog-like in morphology, including displaying mottled- or spotted-coloured fur.
A fancy mouse is a domesticated form of the house mouse, one of many species of mice, usually kept as a type of pocket pet. Fancy mice have also been specially bred for exhibiting, with shows being held internationally. A pet mouse is inexpensive compared to larger pets, and even many other pet rodents, but mice are comparatively short-lived: typically only 2 to 3 years.
A working animal is an animal, usually domesticated, that is kept by humans and trained to perform tasks instead of being slaughtered to harvest animal products. Some are used for their physical strength or for transportation, while others are service animals trained to execute certain specialized tasks. They may also be used for milking or herding. Some, at the end of their working lives, may also be used for meat or leather.
The cultural depiction of cats and their relationship to humans is old and stretches back over 9,500 years. Cats are featured in the history of many nations, are the subject of legend, and are a favourite subject of artists and writers.
Rat-baiting is a blood sport that involves releasing captured rats in an enclosed space with spectators betting on how long a dog, usually a terrier and sometimes referred to as a ratter, takes to kill the rats. Often, two dogs competed, with the winner receiving a cash prize. It is now illegal in most countries.
Jemmy Elton Shaw, also known as Jimmy Shaw and James Shaw, was a 19th-century pioneer fancier of the early dog show days, a promoter of dog fighting and rat-baiting contests, a breeder of Old English bulldogs, bull terriers and toy terriers and a contributor in the development of fancy rats.
Bull and terrier was a common name for crossbreeds between bulldogs and terriers in the early 1800s. Other names included half-and-halfs and half-breds. It was a time in history when, for thousands of years, dogs were classified by use or function, unlike the modern pets of today that were bred to be conformation show dogs and family pets. Bull and terrier crosses were originally bred to function as fighting dogs for bull- and bear-baiting, and other popular blood sports during the Victorian era. The sport of bull baiting required a dog with attributes such as tenacity and courage, a wide frame with heavy bone, and a muscular, protruding jaw. By crossing bulldogs with various terriers from Ireland and Great Britain, breeders introduced "gameness and agility" into the hybrid mix.
A working rat is any rat which is trained for specific tasks as a working animal. In many cases, working rats are domesticated brown rats. However, other species, notably the Gambian pouched rat, have also been trained to assist humans.
The Westminster Pit was a well-known blood sport arena in nineteenth-century London, England. It reached a zenith of popularity between 1820 and 1830, and hosted such spectacles as dog-fighting, cock-fighting, bear-baiting, badger-baiting, monkey-baiting, and rat-baiting. A legal enterprise at the time, the Westminster Pit openly declared its activities, ushering notoriety on the district in which it existed.
An exotic pet is a pet which is relatively rare or unusual to keep, or is generally thought of as a wild species rather than as a domesticated pet. The definition varies by culture, location, and over time—as animals become firmly enough established in the world of animal fancy, they may no longer be considered exotic.
A ratter is any dog used for catching and killing rats and similar vermin. Specialized rat-catching breeds are found in many countries. A typical ratter is small to medium-sized and has a short and smooth coat, however a wide range of dog breeds and landraces may be used. The use of ratting dogs is widely considered to be the most environmentally friendly, humane and efficient methods of exterminating rodents. Ratting dogs are considered more efficient than domestic cats.
Abbie E. C. Lathrop was a rodent fancier and commercial breeder who bred fancy mice and inbred strains for animal models, particularly for research on development and hereditary properties of cancer.
Ryders Alley Trencher-fed Society (R.A.T.S.) is a New York City group founded in the 1990s that conducts organized rat catching with ratting dogs. The group was named by founding member Richard Reynolds after Ryders Alley in Manhattan, which was once rat infested, and the trencher-fed pack assembled to hunt. The group often hunts in Lower Manhattan locations like Theatre Alley where garbage is accessible to vermin.
Tiny the Wonder was an English Toy Terrier famous in the City of London in the mid-19th century for being able to kill 200 rats in an hour in the city's rat-baiting pits. At the time, the world record for killing 100 rats was 5 minutes, 30 seconds, held by a bull and terrier named Billy.
