Using this Rogz cat collar is easy. First, adjust the collar to fit your cat's neck comfortably within the 20 - 31cm girth range. You can use the variable load Safeloc buckle to set the holding strength according to your cat's size and activity level. When putting the collar on your cat, make sure it's not too tight. For night - time safety, the reflective materials will do their job on their own, but it's a good idea to check the collar regularly for any signs of wear and tear. If the collar gets dirty, you can gently hand - wash it with mild soap and let it air dry. Always keep an eye on your cat when it's wearing the collar, especially if it's a new accessory. If the collar gets caught on something, the break - away safety buckle should open, but still, monitor your cat closely to ensure its well - being.
