It is the best spray to cover open wounds since the flies can't get through the aluminum spray. Make sure to cover the eyes when spraying. I use it on horses, dogs and sheep.
Better explanation than mine!!!@SageHill Blue-Kote is germicidal and antifungal. It contains gentian violet and acriflavine. Gentian violet is antiseptic/ antifungal/ turn you purple. Acriflavine is antibacterial. Gentian violet is POISONOUS to cats.
Silver spray is just a bandage to keep wound clean while letting it breathe. It also apparently tastes bad to flies. I'm hoping that letting it dry out will decrease itching so she stops making it worse.
