Well, I have a mixture of MF and "other" (as in who knows and who cares)
ferrets.  At the moment, my ferrets have:
 
Gloin: a weight problem (overweight).  He currently has yogies, ferratone,
and the remote control--typical male.
 
Gimli: had a weight problem (overweight), but now is healthy and has
learned to climb.  He currently has an issue to mountain Climbers Monthly
and an energy bar.
 
Fox: had a weight problem (underweight), but is now the dancing queen!
She currently has her walkman on.
 
Willow: a sleight weight problem (underweight), she is gaining, but slower
than her sister.  She taught Gimli to climb, she currently is considering
taking on more students.
 
Clyde: No problems, thought has always been a skinny fert.  He currently
has all the back issues to How to Beg Monthly
 
Bad Beorn Bear: No problems.  He currently has his daily checklist of how
to get into trouble and is adding to it.
 
Minx da Jinx: No problems.  She currently had her note pad out, as she is
the Ruling Ferret's Prodigy
 
Bonnie da Squidget: No problems, other than being tiny.  She currently has
BOTH rainbow sleepers, stole the Hawaiian sleeper, and has my heart in her
wee little paws.
 
My ferrets range in ages (guessing, all rescues) 6 months to 4 years+.  I
expect problems in the future, but hope for the best!
