I agree that you should do all you can for the well being and car of your animal, but given this persons circumstances i think that they've at least tried to get help to it, rather than taking the poor thing to a vet, who isnt specialised in small animals, as the first post said.
In my honest opinion, i would ask on here before i took my animal to a vet who i wouldnt trust with my pet, but i suppose that is just me.

At least she hasn't tried to rehome it like some people do when they know they've got a poorly animal, or get bored.
