What this means for the bowl
Purina Friskies Prime Filets With Chicken in Gravy is on the lighter side: at 810 kcal per kg it has less energy than 68% of the 42 wet cat foods in our list, so the bowl will look fuller for the same calories.
To show how much the food matters: a 10 lb spayed or neutered cat needs about 261 kcal a day. That is 2 × 5.5 oz can of this food, but 1 ¼ × 5.5 oz can of Instinct Original Grain-Free Pate Real Chicken Recipe Wet Kitten Food and 2 ¾ × 5.1 oz can of Royal Canin Feline Weight Care Thin Slices in Gravy. Same cat, same day, very different bowls.
Wet food is mostly water. Gram for gram, the average dry cat food in our list has about 4.7 times the calories of this one, which is why the wet portion looks so much bigger.
