Actually, if you'll look at the numbers you posted for Eukanuba, you'll see
that Totally Ferret *is* slightly better:
 
>"Totally Ferret- Protein(36%), Fat(22), Fiber(1.5), Ash(6.5), Magn(.09)
>                 First 3 ingredients: poultry by-prod meal, rice flour,
>                 poultry fat.  (Recommended for kits and adults)"
 
Eukanuba:
>Protein not less then 34%
>Crude fat not less then 21%
>Crude fiber not more then 2.5%
>Ash not more then 7%
>Magnesium not more then 0.0965%
 
2% more protein, 1% more fat, and 1% less fiber in TF; and a bit less ash.
However, this is only *slightly* better, so Eukanuba does look like a good
food for our fuzzies.
