Main product description Veterinary preparation. Repellent collar for dogs and cats based on the natural substance geraniol with a strong repellent effect against fleas (Ctenocephalides felis) and ticks (Ixodes ricinus). Composition: 5 g/kg Geraniol. Mode of use Place the dog and cat collar around the pets neck. Cut the excess piece from the collar and leave it in the bed or where the animal spends most of its time. However, the animal must not chew the collar! Check that the collar around the neck is loose enough so that it does not strangle him, but still touches the skin. Continuously check the condition and placement of the collar on the animals neck. Effectiveness: From the moment of removal from the packaging up to 3 months. The active substance is gradually released through the pores of the collar into the animals fur and skin. Wetting or wetting the collar does not shorten the duration of action. Warning: Keep out of reach of children. Avoid contact with skin and eyes. Contains geraniol. May cause an allergic reaction.
