Cage confinement all alone can be very lonely. Do you have another ferret you can trust with her to keep her company? When Lily has had surgery (3 times), after a few days, I let Lany stay with her some for company. I KNOW Lany won't hurt her. As for the cats, they may be smelling the bandage/cast and she may smell like a stranger to them. I know that when I even have a band-aid on me, the ferrets all sniff at it and try to bite it off. It may just be the unusual smell that the cats don't recognize. Katharine [Posted in FML issue 2737]
