Input (English): [header] How to choose food for a kitten [title] Consider the age of your kitten. [step] Your kitten won't need to start eating cat food until it's at least four to six weeks old. Before this point, the kitten should still be nursed exclusively by the mother cat. <sep> (A) Kittens from seven weeks to one year old should be eating kitten food. [substeps] Once your cat is a year old, you can transition to adult cat food. (B) In the rare case of a kitten born without a mother cat, the mother cat may be a carrier for the kittens instead of a food bowl. This may cause behavioral issues, such as vomiting or ear infections, that occur as a kitten ages. (C) This gives him nutrition, while his mother cat treats him with affection. The cat food will be especially good for a kitten no longer than five weeks old who has been infected by a disease. (D) Some kittens will start gaining mass over time, but the mother cat may be no longer required to feed it food at all. [substeps] This is especially true of puppies.
