What this means for the bowl
Royal Canin Kitten is on the lighter side: at 367 kcal per cup it has less energy than 67% of the 55 dry cat foods in our list, so the bowl will look fuller for the same calories.
To show how much the food matters: a 4 lb kitten needs about 274 kcal a day. That is ¾ cup of this food, but ⅜ cup of Purina Pro Plan Kitten Complete Essentials Chicken & Rice and ⅞ cup of Kirkland Signature Healthy Weight. Same cat, same day, very different scoops.
A level 8 oz measuring cup holds about 96 g of this kibble. If you have kitchen scales, weighing is more accurate than scooping, because a heaped cup holds noticeably more than a level one.
Kittens need about two and a half times their resting energy until they are a year old. The Merck Veterinary Manual notes that kittens can also be fed free choice. If you portion meals, weigh your kitten weekly and recalculate.
