Back to the discussion about 'holistic' foods. A food cannot be holistic in that it makes no sense of the meaning of the word. You can certainly have a holistic approach to nutrition though - that would mean that you were feeding a food that offered the best chance of good health.
Generally, holistic foods tend to be the natural ones. There's a great new one offered by Whites Premium which might be worth looking at. Salmon & Rice and a light diet, containing salmon oil for the omega-6 and omega-3 balance of fatty acids for skin. It's on offer at Pet Pantry at £29.99 saving a few quid off RRP.
