To Sarah: I can't really comment on the 'tumors' you speak of - that's really a vet question - although I did have 2 ferrets with fat pads under their front legs where they joined the body, and after several biopsies, they were dx'd as just that - benign fat. I do worry about your choice of a low activity cat chow. Ferrets NEED extra fat, and most low active diets contain about or less than 10% fat - way too low for a ferret. Personally, I don't believe that usine a food with less fat will in any way shrink those fat pads, if that's what they are. My advice would be to use a good quality cat or ferret food - like Iams Kitten, Totally Ferret, Proplan Kitten, Marshall Premium Ferret Diet - and have those tumors rechecked by a vet.
