But the length at the water line of a Nimitz class carrier is 1,040 feet... Based on the well known formula for hull speed(1.34x sqrt of the length of the waterline), that puts the max speed of them at about 43 knots... Or right about 50mph. While some designs allow for exceeding hull speed, It's fairly doubtful that a ship the size of an aircraft carrier can utilize those methods. It's possible that they don't have the engine power to make 43 knots, but I bet that they come very close to it.
Actually, most cats will have an estrus cycle (the technical name for heat) within six to eight weeks after giving birth. In rare occasions, a cat will have an estrus cycle within a week after her kittens were born.
Cats can become pregnant within months of giving birth. Although a cat can be spayed at any point, it is best to wait until the litter of kittens is weaned. The mammary glands and uterus will be much small then, making the spay easier and safer. Specifically, six to ten weeks after giving birth your cat can be spayed..ased on some internet searches, mother cats can be spayed about 2 weeks after the kittens are weaned. So when the kittens are 6-10 weeks old would be about right. Linus (Dreamboat #72a) answered on 4/25/11.
