if a hamster bleeds, it means that it might have gotten cut by something in it's cage. (nothing should be sharp in it's cage) If it bleeds that means it is either pregnant or starting to die.
It could or it could just be injured or have a disease
It is very possible that a dwarf hamster may die if you step on it and it has blood from its nose. The hamster can be taken to a vet if you are worried.
It got it's tail caught under a rocking chair rocker!
you take it to the Fuxing vet
the hamster is drawn to be very unheathy
Dies, unless you get her into your Veterinarian.
mourn the loss of your hamster.
It is dead :)
Nothing.
Too me
you go to the vet
the hamster will get pretty scared and bite and eat the snail.
