You can use a cat litter scoop to get the worst spots and then sprinkle in new bedding. You need to make sure you DO NOT distrub the nest in any way. If there is any odor you can always neutralize it with pet odor exterminator candles in the room from PetProductsByRoyal.com

Yes. The hamster's should be separated, the cage should be cleaned completely, and the hamster should receive immediate medical attention or else it may die.
Try not to disturb your hamster and just dispose of soiled bedding but do not clean the cage until it's wet tail is cured. You have to take it to a vet or else it will die
Well first of all there should not be mold in a hamsters cage. Try taking your hamster out of the cage and keep her/him in something else for a while. Scrub his/her cage really well, get hamster "cage clean" to get the stink out. Your hamster should be fine.
It probably has a disease so you should take it to the vet and clean their cage
Once the babies have become independent and are not feeding off the mother. If you handle the babies or put your scent in the cage before this time, the mother will eat the babies.
If you just got a new hamster just put him in his cage. If he doesn't move much, you need to give him some space. (Leave a little light in the room, and prevent loud noises.) If your hamster is old and doesn't move much, be very careful. They are very fragile and have a higher risk of catching wet tail at an old age. (Wet tail is an illness that causes death in rodents.)
Absolutely! Fresh vegetables are great for hamsters. Hamsters love lettuce and would eat it all day if they could. Just make sure you rinse the lettuce well before you feed it to your hamster.
the pungent smell might be a condition called wet tail if so you should check the bottom of your hamster and if the back area is wet and covered with feces you should take your hamster immediately to the veterinarian.
Every 6 days, but its a good idea to remove wet woodshavings from wherever in the cage the hamster urinates every day. or once a week
Wet tail in a hamster is not transferable to a person. When a hamster has wet tail, the main symptom is diarrhea.
You need to clean out the cage once a week. You should not need to bathe your hamster (although I do once every few months). NEVER put anything in your hamster's anus - they poop it all out. If, however, your hamster's nether regions are wet, it may have wet tail (diarrhea) and you should rush to a pet store for a product called DryTail that works well or bring the hamster to a vet immediately.
