<p><b>Italian Vegetable tanned leather Cat Collar:</b></p><p>Vegetable tanned leather (often abbreviated as veg-tan) has been produced for thousands of years. Turning animal skins into leather requires the use of tannins to remove moisture and prevent the skins from decaying. Tannins are natural compounds that can be found in tree bark, leaves, and other plant material. Hides are soaked in this solution for over a month, producing a strong, stiff leather beloved for its durability, earthy smell, and rich color. With time and use the leather will gain a darker and more complex color (called patina).</p><p></p><p> </p><p> </p><p><b>Safety Cat Collar No Bell: </b></p><p> </p><p>We designed the cat collar without bells because a cat's hearing (45-64000HZ) is more than three times that of a human (20-20000HZ), and the high-frequency sound waves from bells at a close range will seriously damage a cat's hearing and make it cranky or depressed. </p><p> </p><p> </p><p> </p><p><b>Cat Calming Collar:</b></p><p> </p><p>Coming from the root of the Earth, <b>Silver Sheen Obsidian</b> creates an energetic grounding energy that brings a feeling of security, positivity, and divine earthly love.
