Sounds like you should take her to the vet immediately...
It definitely sounds like something is wrong, if not IBD than possibly a respiratory infection...
By the way, why the heck would you feed your snake a hamster???
In general you should stick to mice or rats, your snake can get spoiled on the hamsters and not want to take other food. Plus you would be better off feeding frozen thawed rats, rather than live feedings, live rodents can seriously injure your snake if you are not careful...
Besides why a hamster???
