My favorite subject, Almond, walnuts, peanuts, are high in "EFA's" [Essential Fatty Acids] This is necessary for the health of our Fid's. 1/2 tsp of shelled sunflower seeds [white-striped unsalted] or 1 to 1/2 tbsp shelled sunflower seed are a excellent source of needed nutrition, grey't treats. Note: if you mix sunflower seeds or nuts into there daily food, instead of giving as treats, they'll eat them first....As a second side note. LOL: read the ingredients in your favorite pellet, you'll be surprised that there main ingredients are: Corn, [little nutrition, used as a bulk filler] Seeds, nuts, and man-made perspectives and vitamins....Then there processed wit heat, which destroys some of the man-made nutrients they added. Like anything else, moderation....
If you feed your fid's Pellet's or Seeds, you only feed them a small amount, there diet should be mostly Veggies, legumes and grains,[brn rice and beans make a complete protein] a little fruit, egg, chicken/turkey/fish nuts etc. Each species have a different requirement for the amount of Fat, Protein, etc. A 1/8 cup of pellets and the same of seed's plus all there fresh food is a good starting point....Jay d
