Dwarf hamsters never usually get big. My female hamster was only about 3 or 4 inches long. Hope this helped! (:
About
Male hamsters tend to be less aggressive and protective than female hamsters.
Pretty big
When i chose my hamster i researched it and i found that males are friendlier than the females. They can only be housed with hamsters from the same litter though.
Dwarf hamsters typically weigh between 1-2 ounces (28-56 grams) when fully grown. The specific weight can vary slightly depending on the species and individual genetics, but this is a general range for most dwarf hamsters.
Very small.... but they are cute
Yes, they are very vicious for their size.
All hamsters have pouches located right where the cheeks would be. The opening to the pouch is located in the mouth so that is why a hamster would be spitting out food and placing big pieces of food in their mouth.
Only if it is a dwarf with a dwarf
the male hamster will choose one female hamster and the left one will die
Hamsters are usually pregnant for 16 days in a syrian hamster and 30 days in a dwarf.
If the male is with the female when she is in heat, they will mate. It's pretty much a given. They should be separated, inbreeding leads to weak litters.
