Roborovski hamster

Last Saturday, I just bought 2 with different sex. The male one is very fat, the female one a little bit small. I bought a pink house for them, and they just eat, sleep and play, some more mess around and scatter the shit all around.I did not take thier picture because when I enclose them with hand, they attempt to flee, and shrink their head into my palm. First day I bought them, the male one I try to tame it, however, he was too scared and shit,zzz.

A little bit of Description:

About Roborovskis
A)Roborovskis (Phodopus roborovskii) are the smallest of all hamsters
B)Roborovskis are the white spots where the eyebrows would be, and the lack of the dorsal stripe seen in all other dwarf hamsters
B)three and a half years of age - the longest of any domestic hamster

Habitat and Diet
A)Roborovskii hamsters live in the wild around the Gobi Desert, throughout Mongolia's desert steppe and parts of northern China
B)highly efficient in their use of water (as evidenced by how they may pass particularly concentrated urine)
C)steep tunnels and they live between 60 and 200 cm below ground.
D)They will eat vegtables, fruit, and plants, but they will eat meat and insects. Therefore, they are omnivores

Pet Ownership
A)Roborovski hamsters are very curious, easily startled, and generally timid, as well as very active
B)They also don't speak or squeak as much as most hamster species
C)If enclosed in a hand, will bite or nip in attempt to escape

Housing
A)Grow to be on average 4.5 cm long—roughly the length of an adult human thumb
B)They are noctural.

Breeding
A)Reach sexual maturity as early as 5 weeks
B)usually do not breed until they are older
C)Females should not mate until they are closer to 4 months old, though males can breed at 3 months
D)gestation period of Roborovski hamsters is usually 20-22 days, but can be up to 30 according to some sources
E) Litters are usually small, being typically of 4-6 pups, though larger litters have been reported. Pups can be weaned at 21 days; this is also a good age at which to separate male pups from females

Mating
A)Telling female and male Roborovskis apart is not easy
B)The two sexes have different openings: female openings are very close together and may even look like just one opening, while male openings are further apart. Males usually have a visible scent gland near the navel, above the two openings - this looks like a yellowish stain
C)Failure to separate Roborovskis is likely to lead to pregnancy at about five weeks
