Using this harness and lead set is easy. First, adjust the harness to fit your cat's girth. The adjustable feature allows you to get a snug but comfortable fit. Once adjusted, put the harness on your cat like you would a vest, making sure it sits correctly on their body. Then attach the lead to the harness. When taking your cat out, always keep an eye on the lead and your cat to prevent any accidents. The Break Away Safety Buckle is there for your cat's safety, but don't rely on it as a substitute for careful supervision. For maintenance, you can simply wipe the harness and lead with a damp cloth to keep them clean. Avoid using harsh chemicals that could damage the reflective materials or the webbing. Store the set in a dry place when not in use.
