Your question is not very clear. Do you mean of the same type of hamster? e.g are bigger syrians likely to live longer than smaller syrians,or are syrians likely to live longer than dwarfs or Russians for instance?
No.
Usually, smaller dogs live longer than bigger dogs.
No Roborovski hamsters live longer.(Robo sounds like robot so it figures.)
no, bigger animals have more bone so their stronger and can live up to foe's. smaller animals perhaps give out faster
No, hamsters only live about 3 to 4 years.
No
it depends. if you have a bigger rabbit they usually live for at least 5 years. smaller rabbits usually live for 7 or longer. by smaller i mean your 4 class breeds and bigger are your 6 class breeds.
Hamsters are not particulary known for living in forests, they live underground in the wild.
yes they are
yes they are because it will live longer and will eventually eat the smaller and weaker animal.
hamsters tend to live about 2 years, but they can live longer.
by normal, if you mean sirian hamsters then the main difference is that Chinese hamsters belong to the dwarf hamster species, which are considerably smaller and arent as friendly (believe me, i know, i own two!).
