How Many Calories Should You Eat on Average? An average woman needs to eat about 2000 calories per day to maintain, and 1500 calories to lose one pound of weight per week. An average man needs 2500 calories to maintain, and 2000 to lose one pound of weight per week. However, this depends on numerous factors.
The early stage. You might be surprised to know that a cat can get morning sickness during the early stage of her pregnancy. For the first two weeks of her pregnancy, your cat may eat less because of the nausea, but by the third week sheâll start eating again and begin gaining weight. By the third week, you may be able to feel the lumps of her developing kittens.
You won't have to wait very long for your next litter of kittens to be born, although it may take a couple weeks before you can confirm that your cat is indeed expecting. Feline pregnancy lasts anywhere from 57 to 67 days, although it may at first be difficult to tell if a cat is actually pregnant. One obvious sign is that her estrus cycle ends. Her body will then begin changing in anticipation of the birth of her kittens. First, her nipples will begin to turn pink or a rosy color.
