A properly fitted collar is a basic safety accessory for any cat, even one that lives exclusively indoors. Breakaway collars are the standard recommendation for cats because they are designed to release under pressure, preventing strangulation if the collar catches on furniture, branches, or fencing. For a large cat like the Highlander, ensure the breakaway mechanism is strong enough to stay clasped during normal activity but will still release under sustained force.
Harnesses are the preferred option if you plan to take your Highlander on outdoor walks or supervised garden excursions. A standard collar should never be used with a leash for a cat, as the pressure on the throat can cause injury and most cats can easily slip out of a collar when motivated. A well-fitted harness distributes pressure across the chest and shoulders, providing secure control without risk of choking. Look for H-style or vest-style harnesses sized for larger cats, with adjustable straps that accommodate the Highlander's broad chest.
Leash training a Highlander requires patience but is very achievable given the breed's confident and curious temperament. Start indoors with the harness alone, allowing your cat to wear it for short periods until they move naturally without resistance. Then attach a lightweight leash and let them drag it around the house under supervision before you begin guiding them. The transition to outdoor walks should be gradual, starting in a quiet, enclosed area before venturing into busier environments.
Reflective or LED-equipped collars and harnesses add a layer of safety for cats that spend time outdoors during dawn, dusk, or nighttime hours. Even in a supervised setting, visibility accessories help you keep track of your Highlander in low-light conditions and make the cat more visible to vehicles if you are walking near roads.
