Using the Rogz NightCat Safety Collar is easy. First, adjust the collar to fit your cat's neck using the Variable Load Safeloc Buckle. Make sure it's not too tight or too loose - you should be able to fit two fingers between the collar and your cat's neck. When your cat is wearing the collar, be aware that the breakaway safety buckle is designed to open if it gets caught. This is a safety feature, so don't be alarmed if it happens. For maintenance, you can hand - wash the collar in mild soap and warm water. Rinse it thoroughly and let it air - dry. Keep the collar away from sharp objects to prevent damage to the webbing and reflective design. Also, regularly check the collar for any signs of wear and tear, and replace it if needed.
