It's no wonder that Mango's daily use spray is preferred by African Greys, Parrots & Cockatoos! They don't add additional skin clogging oil derivatives like other sprays they call preening oils. Birds have enough preening oils of their own. Mango's formulas are a light blend of the naturally occurring essential fatty acids of vitamin A, D & E then blended with aloe vera, sweet natural anise and naturals. All meant to compliment your birds bathing needs. The final product is a soothing moisturizing conditioner that soothes skin, washes away dead skin cells, and reduces the itches. This formula adds vitamins to your pets well being while encouraging your bird's natural preening without clogging skin cells. The superior "aahh, I feel good" spray!
