Does anyone know what an ideal calorie count is for cat food, or does it just vary depending on the cat? The food that I am currently feeding is 366Kcals per cup. One of my cats is four years old, spayed, and weighs 9.6 pounds. She is an ideal weight, according to the vet, but she looks way too skinny to me. My other cat is 10 months old, neutered, and is almost 11 pounds. He has a big build, a huge head and feet, and is starting to look a little chubby--in my opinion. Both cats eat the same grain-free, limited ingredient adult dry food (don't judge--have had to struggle to find food that works for both without puking and diarrhea), and I free feed. I am not sure exactly how much they eat a day. They are nibblers and have little "snacks" all day. Scheduled feedings would not work due to my work schedule. I don't want them to be without food all day. I have two separate sets of bowls with food and water (I empty and refresh the water about 3 times a day), and they each pretty much stick to their own favorite bowls, but the kitten will sometimes nibble out of both. He seems to eat a lot more than my adult female cat. My "little guy" has never been able to be on kitten food (long story), but the vet does monitor his weight to make sure he is growing, and he definitely is. Back to my original question: Is 366 calories a number that could work for both cats?
