Using your Rogz Reflective Kiddy Cat Safety Collar is super easy. First, measure your cat's neck to ensure it falls within the 16.5 - 23 cm (6 - 9 inches) range. Then, fasten the collar around your cat's neck, adjusting the buckle to the appropriate holding strength. Make sure it's not too tight or too loose. When your cat is wearing the collar, the reflective materials will work their magic at night, making it easier for you to spot them. If the collar gets caught on something, the break - away feature will kick in and let your cat escape safely. As for maintenance, you can gently wipe the collar with a damp cloth to keep it clean. Check the buckle regularly to make sure it's in good working condition. Avoid exposing the collar to harsh chemicals or extreme heat, as this could damage the materials. Enjoy peace of mind knowing your cat is safe with this collar.
