Yes, at least in some cases.
Many disease-causing organisms are specific to a certain ... er ... species, or at least to a group of closely-related species, and cannot thrive, or in some cases even survive, within others.
However, there are a few which are less particular. Diseases that can be transmitted from animals to humans are called zoonotic.
One of the most widely-known zoonotic diseases is rabies, which can infect essentially anything warmblooded (it is not known to infect birds in nature, but it has been done in experimental laboratories).
How could humans have impact on hamsters
When you get your hamster, it should already be healthy and clean. When your hamster gets lice, that means they got it from you or any of your friends or family.
all hamsters have fur exept for hairless hamsters and hamsters with a certain kind of skin disease.
Like humans.
humans can
Hamsters don't do that. You must have a evil zombie hamster.. D:
You do know that humans and hamsters aren't the same, right?
A flea may get on a person, but they do not infest them. Also, hamsters do not usually get fleas. If they do, you will be able to visably see them and pick them off with your fingers. If they are scratching a lot, it is more likely that they have mites.
Hamsters are mammals and (normally healthy) baby hamsters are born alive, just like humans and other mammals.
Just like humans.
humans, cats, hamsters
No... unless they have picked up a disease from something.
