Ideally, I prefer that your pet receive all the nutrition he or she needs through the foods they eat. But that's not always possible.

The best of diets – even a raw, species-specific diet – can come from soils that are depleted or from lower quality food sources. Sometimes, the food simply loses many of its nutrients through processing and storage.

And most commercially available pet foods, even if they're "fortified" to meet AAFCO (Association of American Feed Control Officials) standards, contain synthetic vitamins and minerals which have their place, but are further removed from naturally derived supplements.

That's why I often feel it’s important to offer your pet two of nature's most nutrient-dense dietary supplements – the microalgae spirulina and astaxanthin containing microalgae. SpiruGreen for Cats & Dogs is a unique complex that contains both of these supplements that are great for cats and dogs.
