5 pound kittens are still babies, but since they’re indoor only cats, you don’t need to feed them as much as an outdoor cat. A good rule of thumb for feeding a kitten is that the food should be at least half of its body weight each day. For instance if your 5 pound kitten weighs 2 pounds, it would eat about 1/2 ounce (about 14 grams) per meal. Once your little one is older this amount can increase to around 1/3-1/4 cup per meal depending on their size and activity level. You can find out how much to give your cat by using our accurate calculator or simply divide the weight of its’ current diet by two then double that number to get an equivalent wet measurement in ounces or grams..
