This collar is suitable for dogs, cats, and small animals. I accidentally bought two of them. They are completely unopened and brand new, but I'm selling them at a lower price than the retail price. If anyone is interested, please feel free to purchase one. By the way, it's the same collar that the black cat in the photo is wearing. It doesn't have a buckle; it's the type that ties with a string. ------------------------------ Brand: KHUSHYOG Condition: New, unopened Size (Neck Circumference): Approximately 17cm - 24cm ------------------------------
