Direct answer: check and comb a British Longhair regularly enough to prevent tangles and notice skin changes. Frequency should follow the individual coat, shedding and tolerance rather than a rigid breed calendar.
Work through the coat gently
Use a suitable comb in small sections, paying attention to friction areas without dragging at knots. Keep sessions brief and positive.
Separate coat volume from body condition
A dense coat can hide weight change. Use veterinary body-condition guidance rather than judging silhouette alone.
Get help before a mat becomes a crisis
Do not cut close to the skin. Pain, bald areas, dandruff, parasites or sudden grooming difficulty deserve professional advice.
A practical furniture note: The Cashmere Comb can support this routine where its current specifications suit your cat and room. Product furniture cannot diagnose or treat a health or behaviour problem.
