Features: OOTDTY Airtag Collar: Our airtag collar holder makes it easy to keep your airtag on you at all times. We use heavy buttons and a heavy-duty strap to ensure that the airtag stays securely on the collar. Comfortable: We use soft pu leather for the base of our collar airtags, which is breathable and flexible. This is an airtag collar that cats will love. Use in all weather conditions: We designed our collar airtag holder to keep your airtag safe from the weather. The pu leather handle on our airtag collar surrounds the petal to protect it from rain, wind and snow. How to choose the right size: To determine the size you need, wrap a soft measuring tape around the widest part of your cat's neck. When measuring, leave a gap for two fingers to ensure that our airtag collar handle fits comfortably. Size Guide: Our three-size adjustable collar fits cats with neck sizes between 7.5 and 14.8 inches (19-37.5cm). Our airtag pet collar fits most cats and small dogs.
