Hamsters are rodents belonging to the subfamily Cricetinae, which contains 19 species classified in seven genera. They have become established as popular small pets. The best-known species of hamster is the golden or Syrian hamster, which is the type most commonly kept as pets. Other hamster species commonly kept as pets are the three species of dwarf hamster, Campbell's dwarf hamster, the winter white dwarf hamster and the Roborovski hamster.
A derailleur is a variable-ratio bicycle gearing system consisting of a chain, multiple sprockets of different sizes, and a mechanism to move the chain from one sprocket to another. Although referred to as gears in the bike world, derailleurs are technically sprockets since they drive or are driven by a chain, and are not driven by one another.
A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races.
The golden hamster or Syrian hamster is a rodent belonging to the hamster subfamily, Cricetinae. Their natural geographical range is limited to a small arid region of northern Syria and southern Turkey. Their numbers have been declining in the wild due to a loss of habitat from agriculture and deliberate elimination by humans. Thus, wild golden hamsters are now considered Vulnerable by the International Union for Conservation of Nature.
A mobile home is a prefabricated structure, built in a factory on a permanently attached chassis before being transported to site. Used as permanent homes, or for holiday or temporary accommodation, they are left often permanently or semi-permanently in one place, but can be moved, and may be required to move from time to time for legal reasons.
A rolling-element bearing, also known as a rolling bearing, is a bearing which carries a load by placing rolling elements between two bearing rings called races. The relative motion of the races causes the rolling elements to roll with very little rolling resistance and with little sliding.
A caster is an undriven wheel that is designed to be attached to the bottom of a larger object to enable that object to be moved.
The winter white dwarf hamster, also known as the Russian dwarf hamster, Djungarian hamster, striped dwarf hamster, Siberian hamster, or Siberian dwarf hamster, is one of three species of hamster in the genus Phodopus. It is ball-shaped and typically half the size of the Syrian hamster, so is called a dwarf hamster along with all Phodopus species. Features of the winter white hamster include a typically thick, dark grey dorsal stripe and furry feet. As winter approaches and the days shorten, the winter white dwarf hamster's dark fur is almost entirely replaced with white fur. In captivity, this does not usually happen as animals maintained as pets are generally housed indoors and exposed to artificial light that prevents the recognition of short winter daylengths. In the wild, they originate from the wheat fields of Kazakhstan, the meadows of Mongolia and Siberia, and the birch stands of Manchuria.
Campbell's dwarf hamster is a species of hamster in the genus Phodopus. It was given its common name by Oldfield Thomas in honor of Charles William Campbell, who collected the first specimen in Mongolia on July 1, 1902. It is distinguished from the closely related Djungarian hamster as it has smaller ears and no dark fur on its crown. Campbell's dwarf hamster typically has a narrow dorsal stripe compared to the Djungarian hamster and grey fur on the stomach. This hamster may be raised in captivity and kept as a small pet.
A fancy mouse is a domesticated form of the house mouse, one of many mouse species, 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 18 to 30 months.
The Roborovski hamster, also known as the desert hamster or Robo dwarf hamster, is the smallest of three species of hamster in the genus Phodopus. It lives in the deserts of Central Asia, averaging under 2 centimetres (0.8 in) at birth and 4.5–5 centimetres (1.8–2.0 in) and 20–25 grams (0.71–0.88 oz) during adulthood. Distinguishing characteristics of the Roborovskis are eyebrow-like white spots and the lack of any dorsal stripe. The average lifespan for the Roborovski hamster is 2–3 years, though this is dependent on living conditions. Roborovskis are known for their speed and have been said to run up to 6 miles a night.
Hamster wheels or running wheel are exercise devices used primarily by hamsters and other rodents, but also by other cursorial animals when given the opportunity. Most of these devices consist of a runged or ridged wheel held on a stand by a single or pair of stub axles. Hamster wheels allow rodents to run even when their space is confined. The earliest dated use of the term "hamster wheel", located by the Oxford English Dictionary, is in a 1949 newspaper advertisement.
The Chinese hamster is a rodent in the genus Cricetulus of the subfamily Cricetidae that originated in the deserts of northern China and Mongolia. They are distinguished by an uncommonly long tail in comparison to other hamsters, most of whose tails are stubby. Chinese hamsters are primarily nocturnal, however they will stay awake for brief periods, in between naps, throughout the day.
A Toter, or Mobile Home Toter is a tractor unit specifically designed for the modular and manufactured housing industries. Some toters are highly adapted for purposes of delivering or removing mobile homes on smaller home sites. Others look and operate similar to over-the-road semi-trailer tractors with longer wheelbases and sleeper cabs.
In the automotive industry, alloy wheels are wheels that are made from an alloy of aluminium or magnesium. Alloys are mixtures of a metal and other elements. They generally provide greater strength over pure metals, which are usually much softer and more ductile. Alloys of aluminium or magnesium are typically lighter for the same strength, provide better heat conduction, and often produce improved cosmetic appearance over steel wheels. Although steel, the most common material used in wheel production, is an alloy of iron and carbon, the term "alloy wheel" is usually reserved for wheels made from nonferrous alloys.
Hamsterz Life is a hamster simulation video game released by Ubisoft for the Nintendo DS. Hamsterz Life is also known as Love ♥ Hamster or Love Love Hamster in Japan.
Hamster balls are hollow spheres made of clear plastic into which hamsters, gerbils, degus and other small rodent pets are placed, allowing them to run around outside their cages without the risk of running away or getting lost under furniture. They are designed to provide hamsters with exercise. Balls produce an audible rumble across most surfaces, making them easier to locate even when out of sight.
Mountain bike trials, also known as observed trials, is a discipline of mountain biking in which the rider attempts to pass through an obstacle course without setting foot to ground. Derived from motorcycle trials, it originated in Catalonia, Spain as trialsín and is said to have been invented by Pere Pi, the father of Ot Pi, a world champion motorcycle trials rider. Pi's father had wanted his son to learn motorcycle trials by practicing on an ordinary bicycle.
A hamster cage is a cage designed to house hamsters. Hamster cages need to be at least 450 SQ inches of floor space or bigger like the one shown. Although, many experts such as Gernot Kuhnen recommend that hamsters thrive with larger cage sizes.
