Cat collars are accessories worn around a cat's neck, primarily for identification and safety. They often come with a small tag that displays the owner's contact information, helping lost cats find their way home. Collars can be made from various materials, including nylon, leather, and fabric, and are available in numerous colors and designs. Many cat collars are designed with safety features, such as breakaway clasps that release if the collar gets caught on something. This helps prevent choking or injury. Some collars also have bells to alert birds and other small animals of the cat's presence, promoting responsible pet ownership.
