It's okay for a cat to go hungry for a day; cats can survive for 4-5 days. However, if the owner is going to be away from home for an extended period, it's advisable to prepare food for the cat in advance so it can eat when it's hungry. It's not recommended to let a cat go hungry for too long, as it's not good for its health.

A cat's diet plays a crucial role in its healthy growth. A cat's food must contain sufficient protein, fat, vitamins, and other minerals, and these nutrients should be balanced in specific proportions. During their growth period, kittens have specific dietary requirements; they need four times the energy per kilogram of body weight compared to adult cats. They also need to consume more protein than adult cats, and this protein must contain a variety of amino acids.
