Gold hamsters are a specie that are solitary animals, which means they only get together to mate. How ever dwarf hamsters are not solitary animals, they live in small groups and there for they always need to bee one friend with them in the cage. But gold hamsters would kill each other if you put two adults in the same cage. When gold hamster pups are 2 months old, they need to have separate cage each to live in.
When I had my two gold hamsters we had to keep them in separate cages because they would try to kill each other if they got close. It's quite sad actually, since they don't get any hamster-company. This is why I like guinea pigs a bit better..
#8 Oh, the gold hamsters gets all the attention and company from their owners.
#2 They like the company of humans and enjoy to get cuddled and petted by their human companion. The owner is actually the only company what the gold hamster likes. Of cause, you need to tame them first, get them to trust you and like being touch by you and hold by you. Other wise they will run away when you try to get them or they will give you a little bite to defend themselves. But other wise, the only company they enjoy is the company of their owner.
