The BIO Band collar is a natural product made with essential oils and neem extract that provides 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 bites by ectoparasites, so some ticks may remain attached to the animal. It is not deactivated by water or humidity and does not affect the animals sense of smell. The BIO Band collar contains Margosa extract (Neem oil), known for its insect repellent properties, and Lavender oil, which provides a pleasant fragrance while having repellent properties. Due to its manufacturing process, this collar ensures a continuous release of Margosa and Lavandin extract. Instructions: Loosely fasten the strap around your cats neck, allowing two fingers to fit between the neck and the collar. Trim any excess length. For adolescent and growing cats, check the collar occasionally to ensure it fits properly. The collar includes a safety mechanism that allows it to come off if it gets caught on something. Composition of ingredients Margosa extracts, Pennyroyal essential oil, Eucalyptus essential oil.
