Are you feeding the kitten dry kitten food?
Does it have any feeding recommendations on the bag?
Your little one needs to be eating kitten food because adult food does not have the proper amount of nutrients she needs. Do you feed 3 teaspoons of food at each meal or 1 teaspoon 3 times a day? Is it a standard teaspoon or a heaping spoonful?
Does the wet food have feeding recommendations on it?
How much does the kitten weigh?
