The BIO Band Collar is a natural product made with essential oils and neem extract that provide repellent properties against fleas, ticks, and mosquitoes. It is a waterproof and repellent collar specially designed to protect cats from insect bites and lice, including mosquitoes, ticks, fleas, lice, and sand flies. The collar is effective for 3 months. However, it is specially formulated to repel insects and prevent ectoparasite bites, so some ticks may remain attached to the animal. It is not deactivated by water or moisture and does not impair the animals sense of smell. The BIO Band collar contains Margosa extract (Neem oil), known for its insect-repellent properties, and Lavandin oil, which provides a pleasant fragrance while also possessing repellent properties. Thanks to its manufacturing process, this collar ensures a continuous release of the Margosa and Lavandin extract. Instructions: Loosely fasten the strap around the cats neck, allowing two fingers to fit between the neck and the collar. Cut off any excess length. For adolescent and growing cats, check the collar occasionally to ensure it maintains the correct fit. The collar includes a safety mechanism that allows it to detach if caught on something. Ingredients Composition Margosa extracts, Pennyroyal essential oil, Eucalyptus essential oil.
