You don't need two dwarf hamsters for one to thrive, since hamsters are quite solitary and territorial. (They generally attack a partner if they have to live together). However mathematically owning two increases the probability of one thriving (because there's two of them, so if one dies early you still have another chance).
A few years back I owned three Chinese Dwarf Hamsters, but there are different types of dwarf hamsters, e.g Russian Dwarf Hamsters. However, if you are thinking of getting dwarf hamsters, I don't recommend putting them in the same cage, as when I had my three, one of them ended up seriously injuring the other one.
it will chew on it and eventually it will destroy it If you're talking about a real hamster and not a robotic one; hamsters are pretty unsophisticated when it comes to what they eat. We had a litter once that had one little one that had a bad foot, and the other hamsters ate it - I mean, ALL GONE! It was a little gross, but what do you do? Sorry, but you can't put a Syrian hamster with a Roboroski hamster, because although Roboroski hamsters are social, Syrians are not and will amost definitely fight.
Dwarf hamsters clean themselves. I own one and watch him clean himself all the time. Dwarf hamsters clean themselves by pulling both paws from the back of their neck forward.
No, you can have just one and it will be perfectly fine.
no, teddy bear hamsters are very territorial and will fight the other hamster.
yes
If they are Roborofskis or Winter Whites, then the answer is a definite yes. These dwarf hamsters are very social, and require the company of at least one of their own kind. However, do not put two different species of dwarf hamsters in the same cage. They will fight. Also, unless you intend to breed, only put hamsters of the same gender in one cage, or else you'll have a hamster population explosion!Also, do not put a Syrian with a dwarf hamster.
Only one is born at a time
If the 1 year old hamster is a syrian hamster DO NOT put another hamster with it. They are hamsters that NEED to be alone. If it is a dwarf, hamster, it might be ok. Dwarf hamsters like having each others company. However, if the 1 year old hamster is not use to other hamsters, it might not go over to well.
You may have 4 dwarf hamsters in a cage but not Syrian hamsters because they will either fight to their death! Or mate.....
It's mites. Talk to a vet.
Iv'e had one of these before but its just how they look
