During a cat's labor and delivery period, it's recommended to provide her with highly nutritious food to ensure adequate nutrition and maintain her health. Here are some foods that can be fed to a cat during this time:
* Dry cat food and wet cat food: These are cats' usual favorite foods, providing enough protein and fat to meet their energy needs.
* Meat: such as chicken breast, fish, lean beef, lean lamb, etc. These foods contain high-quality protein and essential amino acids, which help support the mother cat's milk production and recovery. 
* Hard-boiled eggs: Eggs are rich in nutrients such as protein, fat and vitamins, which can promote milk production in mother cats.
* Vegetables and fruits: such as spinach, cabbage, carrots, apples, etc. These foods are rich in vitamins and minerals, which help improve the mother cat's immunity and promote digestion.
* Pet milk powder and nutritional paste: These can provide extra nutrition, especially for mother cats with poor appetite or who need extra nutrition.
It's important to note that during a cat's wombing period, avoid feeding her too much oily or high-calorie food to prevent obesity and indigestion. Additionally, always ensure the food is clean and fresh to avoid food poisoning and other health problems.
