Rooster/Cancer and Pig/Cancer meet at 88-93%, one Cancer temperament in two animal natures. Both are homebodies to the bone; the Rooster keeps the house immaculate and the Pig fills it with laughter, children, and unreasonable amounts of happiness.
Pig/Cancer is so happy so much of the time that other signs envy it, and its thirst for the pleasures of the honeymoon suite is famously unquenchable; Rooster/Cancer means well, loves hard, and shows it by making the nest gleam. Two Cancers build the same home from two directions, and it holds.
The shared Cancer heart hears intention, which saves them, because Rooster/Cancer's abrasive tongue can come across as just plain mean when it only meant well. Pig/Cancer absorbs the sandpaper with a grin and answers gently, teaching by example.
Friction lives in criticism. Rooster/Cancer can treat every independent opinion as a species of personal treason and polices tidiness relentlessly, while Pig/Cancer would rather waver in the wings than fight, so resentment can hide behind that famous glow.
Pig/Cancer teaches Rooster/Cancer that a lived-in home beats a spotless one, and Rooster/Cancer pushes Pig/Cancer to claim one achievement that is entirely its own. Each gives the other's domestic instinct its missing half.
At 88-93%, Rooster/Cancer and Pig/Cancer are a natural match, two nest-builders under one sign, provided the Rooster's sandpaper stays on the furniture and off the Pig.
