American Wirehair

The American Wirehair boasts the longest lifespan on this list at 14-18 years, offering more years of companionship than the Arabian Mau's 12-14 year range. Its wiry coat is hypoallergenic-friendly, and it earns a dog-friendliness of 5 and energy level of 3, meaning it craves human touch without being hyperactive — 30% less energetic than the average breed here. This breed proves that a calm cat can still be deeply affectionate.
