Using the Kool Kat Collar is super easy. First, measure your cat's neck and add 2 inches to get the right size. Then, buckle the collar around your cat's neck at the desired spot on the soft webbing. The safety stretch feature means the collar won't be too tight. When it comes to maintenance, you can use a mild soap and water to clean the collar if it gets dirty. Let it dry completely before putting it back on your cat. Make sure to regularly check the bell to ensure it's still attached and working. Also, keep an eye on the buckle and D - ring for any signs of wear. If you notice any damage, it's time to get a new collar for your cat's safety.
