Mother cats will typically lose weight while nursing their kittens. To prevent the cat from losing too much weight, you should begin feeding her more than normal in the final third of her pregnancy. Feeding her too much before the last third of a cat's pregnancy can lead to her become overweight and that can make giving birth more difficult. A mother cat's body weight may have increased by 40 to 50% by the end of her pregnancy. After your cat gives birth, you should continue to feed it more than she typically eats. She will need more calories, since she is now providing energy to her kittens by nursing them. The exact amount of food a nursing cat needs will vary in proportion to its litter size.

To ensure quality, you can also look for a cat food that has been certified by the Association of American Feed Control Officials (AAFCO). A nursing cat will need lots of protein to keep herself healthy, and to provide nutrition to her kittens. Quality cat food will normally provide enough protein. However, if her kittens are especially noisy or mobile, it can be a sign that the mother is not getting enough protein. If in doubt, feed kitten-food to the mother cat while she is nursing. Kitten food is higher in calories, calcium, and protein. Most kittens will...
