Should you continue to mix in high quality cat food if you start to feed
Totally Ferret?  NO
 
The answer to the smelly urine.  It could be the mixture.  If one or both of
the foods have corn gluten, soy, or high levels of wheat gluten, it could
affect the urine smell as well as the pH.  TF is high in animal protein and
should help reduce the odor.
 
Thanks for your questions.  Sorry we were not able to answer sooner.
