ON TRAVAILLE POUR LE HAMSTER - LES P'TITS BONZOMS

Product Information

Years later, animals of this original breeding colony were exported to the United States, where Syrian hamsters became a common pet and laboratory animal. Females are in estrus about every four days, which is indicated by a reddening of genital areas, a musky smell, and a hissing, squeaking vocalisation she will emit if she believes a male is nearby. The Roborovski hamster ( Phodopus roborovskii) is extremely small and fast, making it difficult to keep as a pet. Female Chinese and Syrian hamsters are known for being aggressive toward males if kept together for too long after mating.

Some activists attempted to intercept owners who were on their way to turn in pet hamsters and encourage them to choose adoption instead, which the government subsequently warned would be subject to police action. When examined, female hamsters have their anal and genital openings close together, whereas males have these two holes farther apart (the penis is usually withdrawn into the coat and thus appears as a hole or pink pimple). million years to the Middle Miocene Epoch in Europe and North Africa; in Asia it extends 6 million to 11 million years.All hamsters are excellent diggers, constructing burrows with one or more entrances, with galleries connected to chambers for nesting, food storage, and other activities. Fritzsche indicated although some species have been observed to show more nocturnal activity than others, they are all primarily crepuscular. Wild hamsters will also appropriate tunnels made by other mammals; the Djungarian hamster, for instance, uses paths and burrows of the pika. Comparative studies of domestic and wild Syrian hamsters have shown reduced genetic variability in the domestic strain.

If breeding hamsters, separation of the pair after mating is recommended, or they will attack each other. This kind of thermoregulation diminishes the metabolic rate to about 5% and helps the animal to considerably reduce the need for food during the winter. Although pet hamsters can survive on a diet of exclusively commercial hamster food, other items, such as vegetables, fruits, seeds, and nuts, can be given. The best-known species of hamster is the golden or Syrian hamster ( Mesocricetus auratus), which is the type most commonly kept as pets.The name "hamster" is a loanword from the German, which itself derives from earlier Middle High German hamastra. They are extremely susceptible to rapid temperature changes and drafts, as well as extreme heat or cold. The coat of the winter white dwarf hamster ( Phodopus sungorus) turns almost white during winter (when the hours of daylight decrease).

Neumann, K; Michaux, J; Lebedev, V; Yigit, N; Colak, E; Ivanova, N; Poltoraus, A; Surov, A; Markov, G (2006). Both Syrian and Russian hamsters mature quickly and can begin reproducing at a young age (4–5 weeks), whereas Chinese hamsters will usually begin reproducing at two to three months of age, and Roborovskis at three to four months of age. After that, she was happy since all she wanted from him was hardcore sex, which he provided with the satisfaction of his large cock.The hamster tail can be difficult to see, as it is usually not very long (about 1⁄ 6 the length of the body), with the exception of the Chinese hamster, which has a tail the same length as the body. In the wild, the burrow buffers extreme ambient temperatures, offers relatively stable climatic conditions, and protects against predators. These include the maned hamster, or crested hamster, which is really the maned rat ( Lophiomys imhausi). Hamsters tend to love peanut butter but it is important to feed it to them carefully because this sticky food can get stuck in their cheeks.
