This cat collar is handmade using reinforced cotton and top quality contoured hardware. Reinforced cotton makes a great collar material because it is soft, light, as well as sturdy. It is also machine washable which all pet owners know is a "must have!". We use breakaway clips on our cat collars for your kitty's safety. The bell can easily be removed if you prefer. The large cat collars are: 9"- 15" long and 3/8" wide and the small cat collars are 6.5"- 10" long and 3/8" wide. This collar comes with a bell, charm, both, or none. If you select "none" the collar will still include a ring. We estimate that the large size generally fits all adult cats and the small fits most petite cats and kittens under 10 lbs but we recommend that you measure your cat's neck with a soft tape measure to be sure. For your pet's safety we recommend that you monitor your pet while using any pet products and discontinue use if you notice any kind of damage to the hardware or the straps.
