Now, I'm not sure if I can specifically say this for hamsters only, but pretty much, based on experiences, I can tell that the reason why animals in general have fur, is to keep it warm.
you have to clean there ears regualy
no. it is just how theie ears usually are!!!
they are angry or sad
Well ,my hamster had babies and their ears will open in two to three weeks.Hope I helped.
Hamsters hear with their ears, just like people do.
some like to be scratched behind the ears but not all.Always remember to scratch gently
no, but as they get older they lose a bit of hair around their ears and on their bellies
it can spit but it cant fall off

Yes, on the underbelly, around the legs, ears, nose and maybe eyes.
It means that ur hamster is sad, so play with it more!!!
