Tear Stain Powder for Dogs and Cats This is a powder for dogs and cats. This is a genuine product that was imported privately from overseas. I have an Exotic Shorthair and was having trouble with tear stains, but by applying this regularly, the staining became less noticeable. How about this for pets whose eyes tend to get dirty? I used a human eyeshadow brush to apply it to my cat. This bottle is brand new and unused!
