I too have been wondering about canola oil, walnut oil and the other oils I see at the grocery store because my two dont seem to like the ferretone cut with olive oil. Boris kinds of shakes his head and does a Ptooey! He keeps sniffing because of the ferretone but doesn't really lick it all up like usual. So tonight I bought fish oil capsules (cod liver oil had vit A in it or innately part of it). The fish oil was just fish oil - whether it has vit A naturally I don't know. Anyway - they seemed to like it straight! I cut open a couple of capsules and they lapped it up. Sort of stinky but hey, anything for the ferrets:) My question is, since cod liver oil is a laxative - is fish oil bad because of that? Ferretcoat (similar to ferretone but what I use since that's what their used to) has cod liver oil in it. Am I really getting away from vit A? Or because its an "animal" product vs. vegetable like olive oil does it naturally have vit A? Mary, Boris and Giesela [Posted in FML issue 1863]
