>he has 2 white circles in his eyes
 
Dear X:
 
Cataracts are generally not treated in ferrets - while they could
conceivably be removed by a veterinary ophthalmologist, it is usually
very costly and the difference in life quality is not all that much.
 
Blind ferrets get around remarkably well, and ferrets with cataracts are
probably minimally sighted, with the ability to determine light rooms from
dark rooms, upcoming walls, etc.
 
In a perfect world where everyone is independently wealthy, cataract
surgery would be an interesting proposition.  But the improvement will
likely be slight at best, the chances of complications are there, and
with four ferrets, you will likely be better off putting that money toward
other surgeries in the future.
 
With kindest regards,
Bruce Williams, DVM
