Amici e Felici Disabituante Crystals is an outdoor product, suitable against the bad habits of cats and dogs outside your home. To teach them about places that are inaccessible to their needs, just sprinkle a small amount of product on the ground. This repellent is produced in aqueous crystals that release a very penetrating perfumed essence, which disturbs the sense of smell without being harmful to animals or humans. Amici e Felici Disabituante Cristalli is available in 1000 ml bottles.
