Material & Color: The material is cloth, so it's soft and gentle on cats, and it's also breathable. It's lightweight, so it won't stress your cat. Available in three colors: red, green, and navy. Adjustable Size: The collar size is adjustable between 18cm and 28cm, allowing you to adjust it to the appropriate length for your cat. The safety buckle design releases when force is applied, so if your cat gets caught on branches or wires when going outside or escaping, the collar will come off easily. I bought it because it's very cute, but my cat doesn't like collars. Only tried it on. I hope someone will take it.
