What this means for the bowl
Royal Canin Kitten Thin Slices in Gravy sits in the middle of the 42 wet cat foods we track, at 893 kcal per kg.
To show how much the food matters: a 4 lb kitten needs about 274 kcal a day. That is 3 ½ × 3 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 3 × 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 4.2 times the calories of this one, which is why the wet portion looks so much bigger.
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.
