Ferret still acting up!?

MY GREANDPARENTS OWN 2 FM. FERRETS. SILVER AND GOLDY. WELL SILVER IS A LIMP NOODLE AS GOLDY IS THE OPPESITE! i was told she may have liver probllems. the vet gave meds but they arent changing her act. when ever i go to pick her up her body falls over limp before i even touch her. when i pick her up she goes limp. goldy srawls her legs apart to land a fall if i dropped her. when goldy falles she lands on her feet (usually) silver just limps out. doesnt even stiffen. their eyes where all watery like they where crying. goldy was laying down looking sad like she kows somthins wrong. (It aint watery eyes from a cold!) does she have a disease? when goldy plays she bounces and bites hard. silver RARELY plays. when she does she bounces up and doesnt land right. she ends up falling over. silver is 2 and goldy is 1. what could be wrong? u can e-mail for pics of how limp she is acting and comare to goldy. e-mail 4 pics if u need too see them. wildwhiskers250@yahoo.com
PLZ help?!?!?!?
Answers:
Try a different vet - one that is ferret knowledgeable. This is not normal behavior at all. Bloodwork is needed and a diagnosis other than "might have". Do this quickly, treat it as an emergency, because it is. Ferrets are very good at hiding weakness and illness, so by the time obvious symptoms are present the problem is well advanced.
