How much should my kitten eat depends on her age and growth rate. Your veterinarian will be able to help you determine what is appropriate for your kitten’s current health and growth needs. Be sure to watch the amount of food she consumes, as kittens may eat more than they need or indicate by vomiting or refusal to eat. Make an effort not to limit her food intake: this can lead to ill-health and obesity, which can cause serious complications in later life. Kittens also need a lot of water so try mixing it with their diets, rather than just providing them with water alone; this helps keep their kidneys working properly (for example if they are dehydrated).
