Those who want to stick to whole or mostly whole foods while adding calcium and Omega 3 Fatty Acids can consider giving small amounts of sardines with their bones. Large amounts of certain marine fish or crustaceans (esp squid) over time backfire by causing Nutritional Steatus (Yellow Fat Disease) BUT smaller amounts are healthy, even if there is odor, and can promote better nutritional balance. In fact, if needed, it can even be used as a sick food for a ferret; it's not ideal but it made all the difference for a fussy-when-sick one of ours who otherwise would not have gotten over a particularly nasty hump in her road of life.
