Roxie has improved so much since my last post it can only be described as awesome. She can play for hours on end without running out of steam. I see no signs of hind-leg weakness. Roxie has gained ALL of her weight back and eats like a little pig. I would have to say that from all outward appearances, Roxie has made a full recovery and is enjoying life more now than in the past 2 years combined. The only difference I have noticed in behavior is her STRONG desire to be held and hand fed occasionally. Roxie wants lots of human contact and does not resist being a lap pet (unlike all other ferrets I've handled). I love Roxie like no other pet I've ever had and every penny I've spent (thousands) towards her recovery was absolutely worth it.
