Of these hamsters, many are rarely kept as pets. The 5 most commonly-kept types of hamsters for pet owners are Syrian hamsters, Campell’s Dwarf hamsters, Roborovski Dwarf hamsters, Winter White Dwarf hamsters, and Chinese hamsters. 5 Common Pet Hamster Species

Genus Cansumys (Gansu hamster) 1 species from northeastern China (Kansu province), known only from 3 specimens collected during the 20th century. It’s found in China and Mongolia where it lives in burrows beneath desert shrubbery. 18. Tibetan Dwarf Hamster Syrian hamster (Mesocricetus auratus) belongs to the Cricitinae family of hamsters and is commonly known as the golden hamster. These animals originated in Syria and are naturally found in the arid, temperate southeast Europe and Asia Minor ( 5). Syrian hamsters currently used as laboratory animals originated from a litter captured in 1930 ( 5, 6). There is mounting evidence that the Syrian hamster is highly similar to humans in anatomy, physiology, and pathology ( 7– 9). Their similarity is especially valuable in terms of the similarity of pathophysiology, i.e the occurrence, development, symptoms, pathology, and outcomes of disease ( 10). Syrian hamsters have a short reproductive cycle, are docile, and are easy to raise and handle ( 8, 11).There are 19 officially recognized types of hamsters that are a part of 7 different genera. The first 5 hamsters listed are hamsters that are commonly kept as pets. The following 14 types of hamsters listed are mostly found in the wild and are almost never kept as pets. 1. Syrian Hamster This nocturnal species lives solitarily in complex burrows where it stashes and eats seeds, legumes, vegetables, grasses, and insects. 17. Sokolov’s Dwarf Hamster

While most dwarf species are limited in their colors, this species can come in a wide variety of different colors and sheens. They’re also very bold, friendly, active, and fun to watch. They Grey Dwarf hamster has an average body length of 4 inches with a furry tail that’s about 1/3 of that length. Its fur is brownish-grey with white underparts. It also has large ears and a flattened skull.The Tibetan Dwarf hamster has a body length of about 4.1 inches with a tail reaching up to 1.5 inches. 19. Turkish Hamster Coloration is relatively muted, with a sandy brownish-grey dorsal coloring and light grey ventral coloring. 16. Romanian Hamster It has an average body length of about 4.3 inches with a tail that’s at least 1/3 of that length. It has a sandy brown dorsal coloraing with a greyish-white ventral coloring. The problem, of course, is that technology has raced out ahead of what the law might have imagined,” Rotenburg said. “So, one thing that may need to happen is to update the law to make clear that this is not permissible." European hamsters are crepuscular and eat seeds, legumes, grasses, vegetables, and insects. They’re frequently solitary. 9. Eversmann’s Hamster

This species digs burrows as deep as 5 feet beneath the ground. It doesn’t hibernate, so year-round it forages for roots, plants, seeds, and hunts insects. 13. Kam Dwarf Hamster It also frequently stands up on its hind legs and loudly screams as a means of communication. 12. Grey Dwarf Hamster This species can cross-breed with Campbell’s hamsters, so it’s difficult to find a 100% Winter White Dwarf hamster. 5. Chinese Hamster All of the other hamsters that are listed have not been domesticated and are rarely kept as pets. That’s not to say that they can’t be kept as pets, but it definitely isn’t recommended.

Therapeutic cancer vaccines are designed to induce tumor regression and eradicate cancer cells by boosting a patient’s immune response and developing durable antitumor memory immune responses ( 102). Dendritic cells (DCs) are the most functional antigen-presenting cells (APCs) in the body and play a key role in coordinating the innate and adaptive immune responses against the tumor ( 103). In 2010, the first therapeutic cancer vaccine (SiPuleucel-T) was approved by the FDA, which improved overall survival for patients with refractory prostate cancer ( 104, 105). Despite their small size, Roborovski hamsters require an extremely large hamster cage and a plethora of different toys. 4. Winter White Dwarf Hamster The Gansu hamster is also a part of the family Cricetidae. It’s endemix to China, and is the only species in the genus Cansumys. 11. Greater Long-Tailed Hamster It digs burrows to an average depth and is active both day and night. It forages for grain and seeds and also hunts insects. 14. Long-Tailed Dwarf Hamster
