If your hamster is jumpy and looking nervous then you should gently stroke it inside of it's cage and then feed it pieces of food out your hand then that way your hamster will come fond of your smell and will be used to you and when you handle it it wont be nervous no more.

Depends. Sometimes it could be something like wet tail wich does kill them. Go and see a vet if in doubt but my hamster did not have a wet tail
