What this means for the bowl
Purina Friskies Surfin' & Turfin' Favorites sits in the middle of the 55 dry cat foods we track, at 392 kcal per cup.
To show how much the food matters: a 10 lb spayed or neutered cat needs about 261 kcal a day. That is ⅝ 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 110 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.
