Hamster Fact Sheet Common Name: Hamster Scientiﬁc Name: Cricetinae Wild Status: Least Concern Habitat: Warm dry areas Country: Originally Syria, Belgium, Romania, Greece, & Northern China Shelter: Burrows & Tunnels Life Span: 1-3 years Size: 2-13 inches depending on species Details The hamster is a category of small rodent that contains over 20 species! They have become extremely popular as small household pets, and like laboratory mice, they have been helpful in scientiﬁc research. They are naturally nocturnal, so they enjoy playing at night, and they can actually learn their own names like a dog. Hamsters love exercised, and that's why a wheel makes for a great toy for them! Hamsters are actually omnivores and can eat insects, but tend to enjoy veggies and fruits. While their sense of smell is great, they have poor vision, so a hamster will generally follow its nose. Cool Facts • Hamsters have special pouches in their cheeks, and they use these to store lots of food! • Hamsters love to explore - a hamster ball is a great way to give your little buddy some exercise, and a chance to discover new places around your home! • The name Hamster comes from the German word "hamstern" which means "hoard". • Right after birth, newborn hamsters are blind until they are about 2 weeks old! Taxonomic Breakdown Kingdom: Animalia Phylum: Chordata Class: Mammalia Order: Rodentia Family: Cricetidae Subfamily: Cricetinae Conservation & Helping Most hamsters are of least concern on the endangered species list. However, the golden hamster found in Syria has the status of Vulnerable. Doing your part to promote the protection of animals and conservation of our planet can help keep all species of hamsters thriving!

Interspecific Attack on Mice and Frogs by Golden Hamsters (Mesocricetus Auratus)
Bulletin of the Psychonomic Society 1977, Vol. 9 (3),186-188 Interspecific attack on mice and frogs by golden hamsters (Mesocricetus auratus) PAUL E. VAN HEMEL Franklin and MarshaU College, Lancaster, Pennsylvania 17604 When tested for their reactions to mice, most male and female hamsters attacked with a pattern typical of hamster attacks on conspecifics_ Females attacked with shorter latency than did males, and the very few hamsters that consistently killed mice were all females. Latencies of attack decreased with repeated testing, even though most attacks were not followed by killing. When tested with frogs, hamsters typically avoided the frogs, although a few showed long-latency attacks and kills. A detailed description of the topography of interspecific attack by hamsters and other closely related groups would be useful as a beginning step in analysis of the function of interspecific attack. Psychologists investigating mouse-killing behavior in If hamsters attack mice and frogs, as rats do (Bandler rats have been primarily concerned with the causation & Moyer, 1970), then a comparison of behavioral and ontogeny of the behavior (polsky, 1975a). Studies phenotypes would be useful as a beginning step for that concentrate on such proximate determinants of functional analysis. Hamsters are known to attack behavior focus on issues quite different from those locusts (polsky, 1974, 1976) and may catch and raised by studies concerned with ultimate questions consume insects (Jacobs, 1945). There has even been about the function, or ecological significance, and the a report of spontaneous attacks by hamsters on mice evolution of behavior (Alcock, 1975). Some authors (Wnek & Leaf, 1973).

Hamsters by Catherine Love, DVM Updated 2021
Hamsters By Catherine Love, DVM Updated 2021 Natural History Hamsters are a group of small rodents belonging to the same family as lemmings, voles, and new world rats and mice. There are at least 19 species of hamster, which vary from the large Syrian/golden hamster (Mesocricetus auratus), to the tiny dwarf hamster (Phodopus spp.). Syrian hamsters are the most popular pet hamsters, and also come in a long haired variety commonly known as “teddy bears”. There are numerous species of dwarf hamsters that may have multiple common names. The Djungarian dwarf (P. sungorus) is also sometimes called the “winter white dwarf” due to the fact that they may turn white during winter. Roborowski (Robo) dwarfs (P. roborovskii) are the smallest species of hamster, and also quite fast. The third type of dwarf hamster commonly kept is the Campbell’s dwarf (P. campbelli). Chinese or striped hamsters (Cricetulus griseus) can be distinguished from other species due to their comparatively long tail. The original pet and laboratory hamsters originated from a group of Syrian hamsters removed from wild burrows and bred in captivity. Wild hamsters are native to numerous countries in Europe and Asia. They spend most daylight hours underground to protect themselves from predators and are considered burrowing animals. While most wild hamster species are considered “Least Concern” by the IUCN, the European hamster is critically endangered due to habitat loss, pollution, and historical trapping for fur. Characteristics and Behavior Both Syrian and dwarf hamsters are very commonly found in pet stores. With gentle, consistent handling, hamsters can be tamed into fairly docile and easy to handle pets, but it is not uncommon for them to be bitey and skittish.

In the Djungarian Hamster (Phodopus Sungorus) K
Effects of short photoperiods on puberty, growth and moult in the Djungarian hamster (Phodopus sungorus) K. Hoffmann Max-Planck-Institut für Verhaltensphysiologie, D-8131 Andechs, West Germany Summary. Male Djungarian hamsters were raised from birth in either long (16L : 8D) or short (8L :16D) photoperiods. In 16L :8D, testes were large (about 400 mg) and showed full spermatogenesis from 31 days of age, the cauda epididymidis contained motile spermatozoa from 35 days and the accessory glands were large and reached their final size at about 60 days of age. In 8L :16D, testes remained small (about 15 mg) and undeveloped up to an age of about 130 days; they then developed to reach normal size and full spermatogenesis. In 16L :8D body weight increased steadily up to an age of about 160 days, but in 8L :16D body weight increase was slower and reached normal values, after a plateau at about 80 days, at about 190\p=n-\260days. Most animals in 8L:16D moulted into winter pelage, and then into the summer pelage; those in 16L :8D kept the summer pelage throughout. Introduction Many mammals show a marked annual cycle in gonadal size and activity as well as in other functions. In a number of species it has been demonstrated that this cycle can be manipulated by photoperiod (for reviews see Aschoff, 1955; Sadleir, 1969; Chapman, 1970; Farner, Lewis & Darden, 1973; Reiter, 1974). Variations ofsexual development, depending on season ofbirth, have also been reported (see Sadleir, 1969; Lincoln & MacKinnon, 1976). Photoperiodic effects in the golden hamster have been studied intensively (Hoffman & Reiter, 1965; Gaston & Menaker, 1967; Elliot, 1974).

4. Genetische Variabilität und Populationsstruktur des Goldhamsters Mesoc- ricetus auratus (Waterhouse) 4.1. Der Goldhamster Mesocricetus auratus Die Gattung Mesocricetus umfasst vier Arten M. auratus, M. raddei, M. brandti und M. newtoni (Wilson und Reeder 1993; Duff und Lawson 2004). Wenige Studien be- schäftigen sich mit der Evolution der einzelnen Arten und deren verwandtschaftlichen Beziehungen (Hamar und Schutowa 1966; Hosey 1982; Niethammer 1982). Neue Erkenntnisse dazu wurden bereits im Kapitel über die Systematik der Cricetinae dis- kutiert. Die mit Abstand bekannteste Hamsterart ist der Goldhamster M. auratus (Abb. 1). Seine Popularität verdankt er seiner guten Eignung als Labortier aber auch seiner Attraktivität als Heimtier. Kurze Generationszeiten und anspruchslose Haltung mach- ten ihn zu einem wichtigen Versuchstier für die biologische und medizinische For- schung (Clark 1987). Abb. 1 Goldhamster (Foto: K. Neumann) Besondere Bedeutung erlangte der Goldhamster für die Chronobiologie (Lowrey et al. 2000), für die er als Modelltier gilt. Bemerkenswert ist auch die Historie der Labor- population des Goldhamsters. Die gesamte Laborpopulation geht auf drei Nach- 99 kommen eines Weibchens zurück, das 1930 in der der Nähe von Aleppo/Syrien ge- fangen wurde (Aharoni 1932, Gattermann 2000). Die Gefangenschaftspopulation beträgt inzwischen mehrere Millionen Tiere. Kein anderes Säugetier erzielte einen solchen Reproduktionserfolg ausgehend von einem so kleinen Genpool. Deshalb wird der Goldhamster mitunter als Musterbeispiel für die erfolgreiche Etablierung ei- ner stabilen Population trotz hoher genetischer Inzucht angeführt (u.a. Frankham et al. 2000). Der geringe genetische Polymorphiegrad der Laborhamster (McGuire et al. 1985; Watkins et al. 1990) schränkte allerdings deren Nutzung für molekulargeneti- sche Untersuchungen wie Genom-Sequenzierungen oder Kartierungs-Experimente interessanter Loci entscheidend ein (Okuizumi et al.

Maternal Behaviour on Golden Hamster (Mesocricetus Auratus )
LUCRĂRI ŞTIINłIFICE MEDICINĂ VETERINARĂ VOL. XLIII (2), 2010 TIMIŞOARA MATERNAL BEHAVIOUR ON GOLDEN HAMSTER (MESOCRICETUS AURATUS ) ILEANA NICHITA 1, MONICA ŞEREŞ 1, C. COMAN 2 1Faculty of Veterinary Medicine Timisoara, 300645, Calea Aradului No. 119, Timisoara, Romania 2NIRDMI Cantacuzino E-mail: [email protected] Summary In ten female golden hamster ( Mesocricetus auratus ), rearing first litters, the maternal activities were study during the observation period (21 days from parturition) divided into two stages: (2 – 10 days and 11 – 21 days). The following females activities were recorded: the frequency of pup grooming (both body and anogenital licking were included), frequency of pup nursing (crouched arch posture over pups), frequency of bringing of food into the nest and frequency of the nest building activity (bringing wood shaving for bedding into the nest and manipulation of bedding material inside the nest. The female under this study displayed a considerable maternal care in the first rearing stage when the pups are very vulnerably and less care in the last rearing stage when the time of weaning is nearest Female displayed all the patterns of direct care of young including nursing and pups grooming. Key words: gold hamster, maternal care The high maternal investment in young characterized the reproduction in mammals (1). In small rodents with altricial pups, immediately upon appearance of the first born, parturient female rodents display a full complement of maternal behaviors, such as pup retrieval, grooming and crouching over the pups. (3). In some rodent species the timidity prevents the virgin female from being a good mother and this is one of the facts for pups killing (2, 5).

General Information on Hamsters
For Public Health Personnel General Information on Hamsters The most common type of pet hamster is the Golden or Syrian Hamster (Mesocricetus auratus), which came from Syria in the mid-19th century. Other less common breeds of hamster include the Chinese Hamster (Cricetulus griseus), and the European or Black-Bellied Hamster (Cricetus cricetus). A Golden Hamster has an average life span of 18-24 months. Hamsters are naturally omnivorous and nocturnal. In 1996, it was estimated that there were 1.9 million pet hamsters in the USA. In 2001, it was estimated that there were less than 900 000. In general, hamsters are not a high-risk pet in terms of the potential for zoonotic disease transmission. However, it is still important to be aware of the diseases they can carry and how to keep both a hamster and its owner as healthy and happy as possible. Obtaining a Hamster Hamsters are often bred in large central facilities and transported from there to various distribution centres and pet stores for sale to the public. Contact with a large number of other animals, and stress during transportation and while in a pet store, can lead to an increased risk of disease transmission and illness in store-bought hamsters. Hamster Management Hamsters have specific dietary and environmental requirements to keep them healthy. Owners should be referred to their veterinarian or other experienced hamster owners for specific details on hamster husbandry, as well as how to handle a hamster appropriately in order to reduce the risk of biting. Hamster Bites All hamsters may bite.
