In what way does the rear end look strange? If there are any real concerns it would be best to get a check up if you can.
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
It can mean a variety of things. It could have injured its paw or it is really tired. It can also mean that you have an old hamster.
You really need to take the hamster to a veterinarian, only they can really diagnose or treat the problem. Not using its legs could indicate a spinal problem.
That's really dangerous, you better go to the vet, you could kill your hamster.
Hamsters can't throw up, so no, not really.
The nicest hamster you could buy is a syrian and a teddy bear hamster they dont bite as much as other hamster do
A hamster will not usually behave in this manner. It could be a sign that she is very sick, or that she has some sort of mite infestation. You really must take her to see a vet.
no your hamster can get sick
It could really be anything, too much exercise, not feeding it, not enough exercise, not drinking enough water, other health problems, anything similar to the above answers,really! (P.S. i had a hamster of my own!)

A strange visitor could be someone unfamiliar or unexpected, such as a new neighbor, a lost traveler, or a salesperson. It's important to approach them with caution and assess the situation before interacting with them.
You can put it upside down but it wouldn't be good for its body or its head and the hamster would crawl sqealing and could bite so dont really put it upside down
