Cat Pregnancy & Lactation: Ensuring Optimal Nutrition for Your Feline Friend

As cat owners, we know that pregnancy and motherhood are crucial periods in a cat’s life. During this time, the queen plays a vital role in providing the energy needed for her kitten’s growth, both during gestation and the early weeks of life. It is imperative that her diet is carefully tailored to meet the high demands of reproduction. At Katten TrimSalon, we understand the importance of proper nutrition during cat pregnancy and lactation.

Diagnosing Pregnancy

The first step in ensuring a healthy pregnancy is to diagnose it accurately. In most queens, gestation usually lasts around 63 to 65 days. One early indicator of successful breeding and conception is a steady gain in body weight, assuming the diet or food intake has not changed. Weight gain typically increases linearly from conception to parturition, unlike in other species where it increases significantly only during the last third of gestation.

The Impact of Nutrition on Reproduction

Proper nutrition is essential for optimal reproduction. Poor nutrition can lead to the failure to conceive, fetal death, fetal malformations, underweight kittens, and impaired immune function in offspring. On the other hand, obesity can also have negative effects on pregnancy outcomes. At Katten TrimSalon, we emphasize good nutritional management throughout reproduction to ensure healthy outcomes for both the queen and her kittens.

Meeting the Energy Demands

One of the most important changes in nutrient requirements during pregnancy and lactation is an increase in energy demand. While many essential nutrients are required at increased levels during this time, dietary energy is often the most limiting factor. Food intake typically fluctuates slightly throughout gestation, with two common periods of reduced food intake. It is crucial to provide a diet that meets these energy demands for the queen to maintain optimal health and support the growth and development of healthy kittens.

Essential Nutrients for Reproduction


Protein is greatly increased during pregnancy. It is important to provide high-quality protein that supplies all the essential amino acids for the growth and development of the fetuses. Meat and organs are excellent sources of high-quality biological and digestible protein. Taurine, an essential amino acid, is also required for normal reproduction and fetal development. Adequate levels of taurine are crucial to avoid complications during gestation.

Fats and Essential Fatty Acids

Fat is beneficial due to the increased energy demand during pregnancy. It provides over twice the number of calories as the same amount of protein or carbohydrates and facilitates the absorption of fat-soluble vitamins. Moderate to high-fat foods enhance lactation performance in queens. Essential fatty acids, such as linoleic acid, arachidonic acid, and docosahexaenoic acid (DHA), are crucial for reproductive success. These fatty acids can be found in various animal tissues and supplemental cold-water fish oil.


Cats are strict carnivores, and their nutritional requirements are primarily met through animal tissues. While carbohydrates are not essential for cats, they can still be converted into glucose through gluconeogenesis. The cat’s ability to efficiently use dietary amino acids for maintaining blood glucose levels negates the need for carbohydrates in their diet.

Vitamins and Minerals

Vitamins and minerals are essential for the proper development and overall health of the queen and her offspring. Vitamin A, D, E, K, C, and B complex are crucial during pregnancy and lactation. Adequate intake of minerals such as calcium, phosphorus, zinc, iron, selenium, and copper is also essential. Fresh water should always be available, as it serves as a carrier of nutrients and aids in milk production.

Feeding for Pregnancy and Lactation

At Katten TrimSalon, we recommend a diet that closely mimics a cat’s natural feeding behavior. A whole prey diet, consisting of whole animal carcass patties, is an excellent foundation for the pregnant and lactating queen’s diet. These patties provide the necessary fat, protein, vitamins, and minerals required during this crucial period.

During the first half of pregnancy, the queen does not require additional food. However, as the kittens’ growth accelerates during the latter half, gradual adjustments should be made to her diet. Meal size should be reduced, and multiple smaller meals should be provided throughout the day. By the ninth week, food intake should be gradually reduced, and supplements should be eliminated.

During lactation, the queen’s demand for energy and nutrients is at its peak. She should be fed as much as she wants, with a focus on providing top-quality food. The diet should include high levels of protein, calcium-rich minerals, fats, essential fatty acids, vitamins, and minerals.


Supplementation should only be used to enhance the diet, not replace foods that are already providing adequate nourishment. Cold-water fish oil can be added daily for its beneficial omega-3 fatty acids. Additional supplementation with vitamin E may be beneficial if the queen requires a high-fat diet during lactation. Raw egg yolk and fatty fish can also be included in the diet for added nutrition and variety.

At Katten TrimSalon, we believe that proper nutrition is essential for the health and well-being of your cat during pregnancy and lactation. By providing the right balance of nutrients, you can ensure the optimal development and growth of healthy kittens. For more information and professional advice, visit Katten TrimSalon.
