Pregnancy and nursing are responsible for many changes in a cat's lifestyle, as well as in her body. You should pay special attention to your cat’s changing nutritional needs throughout the entire reproduction process.
If you are planning to breed your female cat, it is important to assess her body condition well in advance. Because of the physical demands of pregnancy and nursing, starting off with less-than-ideal health can cause problems.
An underweight cat often can't consume enough food to support her and the developing kittens. Overweight cats may experience abnormal or difficult labor because of large fetuses.
A complete and balanced diet that supports a healthy weight and body condition before breeding helps the female cat maintain her health, and that of her offspring, throughout pregnancy and nursing.
The gestation period for cats is nine weeks. Pregnant cats, like humans, gain weight gradually throughout pregnancy. The energy requirements of pregnant cats are reflected by their weight gain. The energy needs of a pregnant cat should gradually increase so that, by the end of pregnancy, the cat is consuming 25% to 50% more than her normal amount of calories.
Pregnant cats lose weight after giving birth. However, their nutritional needs increase dramatically. Energy needs can be two to three times normal, depending on litter size, in order to produce the milk supply that will support the offspring. Water intake is also important for milk volume.
To ensure a nursing cat is getting enough nutrition, give her a nutrient-dense diet, such as kitten food. Without increasing the amount of food at each meal, increase the number of meals in the day. Free-choice feed her, offering unlimited access to dry food.
By 5 weeks, most kittens show an interest in their mother's food. Gradually, the kittens will begin eating solid food and nursing less. At the same time, the nursing cat will usually start eating less. Most kittens are completely weaned by eight weeks after birth. By this time, the mother's energy requirement is back to normal and she should be eating her usual pre-pregnancy diet.
Compared with humans, your favorite feline needs a high-fat, high-protein diet with certain animal nutrients.
Cats usually eat many small meals throughout the day, so they easily adopt a free-choice feeding schedule to maintain their normal body weight. Dry foods, such as IAMS™ Proactive Health™ Healthy Adult - Chicken, are best suited for free-choice feeding because they stay fresh longer.
Cats need nutrients from animal-based protein sources. Providing the vitamins, minerals, protein, and other components found in a complete and balanced pet food can lead to a long and healthy life for your cat. It is important to avoid supplementing your cat's diet, as doing so may lead to a variety of health problems. When selecting a pet food, look for ones that offer the following nutrients:
Animal protein from meat, poultry, fish, or egg sources to maintain strong muscular structure, vital organs, antibodies, and more
Taurine, an amino acid found in meat sources such as chicken and fish, but not in plant proteins, to maintain healthy eyes, prevent heart disease, and promote healthy reproduction, fetal growth, and development
Essential vitamins and minerals such as vitamin A, which can be found pre-formed only in animal tissues, and vitamin E to help support the immune system
A precise balance of fatty acids to help promote excellent skin and coat health
A fiber source, such as beet pulp, that will help maintain your cat's digestive system health.
Pregnant or Lactating Cats
A cat's energy intake should be increased gradually by up to 50% over her maintenance intake through pregnancy. You can use kitten food to provide nutritional support during the last few weeks of gestation.
After birth, the mother cat's energy needs increase by 50% to 75% over normal in the first week to twice normal the second week and to three times during the third week. The third and fourth weeks are the most demanding because kittens are still consuming milk and have not begun to eat dry food. Once kittens begin weaning, the mother cat should be tapered back to normal food portions to avoid unnecessary weight gain.
Avoiding Obesity
Food and energy requirements may vary for your adult cat. In general, indoor cats have less opportunity or need to exercise than outdoor cats. As a result, indoor cats are more prone to obesity, and regular exercise should be encouraged. You may want to control your cat's portions.
