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.
The Association of American Feed Control Officials (AAFCO) was formed in 1909 to establish a framework for uniform regulation of the feed industry. Although not a government agency, AAFCO operates within the guidelines of federal and state legislation including laws administered by the Food and Drug Administration (FDA) and the U.S. Department of Agriculture (USDA).
AAFCO establishes standards or models for regulations aimed at ensuring that manufacturers provide clear, accurate, and consistent information about animal feed, including pet food.
Every year AAFCO issues an official publication called the AAFCO Manual. This manual, in addition to listing ingredient definitions and feed terms, addresses labeling issues such as label format, ingredient lists, nutrition claims, and guaranteed analysis.
These model regulations are different from laws. However a large number of state governments have adopted AAFCO pet food model regulations into state law.
The “AAFCO statement of nutritional adequacy or purpose,” also called a “nutrition claim” or “complete and balanced statement,” identifies which life stage and/or lifestyle the product has been approved for. Under AAFCO regulations, this statement must be substantiated by the manufacturer.
AAFCO recognizes three methods for substantiating the claim:
1. Laboratory analysis
2. Feeding trials
3. Analysis comparable in nutritional adequacy
AAFCO has outlined very specific protocols, or guidelines, for conducting feeding tests. The protocols specify test criteria including such things as:
Each life stage has its own protocol. Life stages are the same for both dogs and cats and are defined as:
A pet food with an 'All Life Stages' claim can be used from weaning through adulthood. This claim is considered an unqualified (absolute) representation of nutritional adequacy. If substantiated through feeding trials, the protocol for gestation/lactation and growth must be performed sequentially, using the same group of animals.
AAFCO regulations state that specific wording must be used when a diet is intended for special nutritional or dietary needs that require the involvement of a veterinarian for diagnosis, management, and follow-up.
Understanding the AAFCO statements for nutritional adequacy can help customers choose a high-quality diet that provides complete and balanced nutrition for the appropriate life stage of their dog or cat.
