Then subtract the 9 kittens that were sold: 21 kittens - 9 kittens = 12 kittens. Then add the number of kittens to the number of adult cats to find the total number of cats: 12 kittens + 6 cats = 18 cats. Then divide the number of kittens by the total number of cats and multiply by 100% to find the percentage of cats that are kittens: 12 kittens / 18 cats * 100% = 66.666...%, which rounds up to 67%. So the final answer is 67.
