We tried out the flavored Cheweasels, and also more Foamy fries.
 
The Foamy Fries still seem to be the strong favorites here, and on
examining their teeth they also seem to work as well for cleaning as the
Cheweasels.  We are seeing pearlier whites in all except when they get
too jealousy guarded by a few.  The ones who chew them the most have the
cleanest teeth.  The stick shape of the Foamy Fries permits our ferrets to
hold them like toothbrushes, which is hilarious to see.  The only problem
encountered so far has been that one will at times get a chewed-off bit
caught temporarily on a tooth.  We have not seen runs from FFs so far.
 
Foamy Fries have a shape that doesn't let them as readily be used in
"fishing pole" games, though I guess they could be with a tight enough
string tied around the middle, but we've found that they are great for
discovering in tubes when a game introduction is wanted.
 
Of the flavored Cheweasels our personal best luck for appreciation among
the ferrets has been for the carob flavored one, followed closely by
banana.  That makes sense simply because our guys already knew these
flavors and smells.  Despite lack of previous exposure to the tastes or
smells of molasses and cheddar those flavors were also accepted but took
a bit of time to introduce.
 
The Foamy Fries are so extremely loved by our crew that we certainly will
be getting more the next time we order from the Ferret Store.  We'd likely
also get the carob or banana Cheweasels preferentially if they wind up
being offered in single favor packs over the original chicken, or the
molasses, or cheddar, but FFs seem to work the very best in our family.
They give them great breath, too!
