You need two measurements: rib cage circumference (around the widest part of your cat's chest) and leg length (from shoulder to paw on the front leg). Use a flexible measuring tape and ensure your cat is standing naturally.
FBMI scores typically range from underweight (below 15) to overweight (above 30). An ideal FBMI is usually between 15-25, but this can vary based on breed and individual cat characteristics.
