The best thing to do is get your cats spayed or neutered. You need to because your cat can reproduce. There are too many cats in the world and we don't need more. It is bad for the females if they have litters. When you get your cat you should get it fixed. Kittens may be sweet but lots of kittens get put down because everybody can't get one and they need space for new animals. I encourage you to get them fixed and get ones from your local animal shelter. If your cat has a litter you should keep the kittens inside away from predators because new born kittens are prey to some animals. After you get your cat spayed or neutered the best thing to do is keep them inside or in the garage for at least three days so it will give them time to wear off the anesthesia. They first may be very wobbly. The best thing to do is keep them in a cage until they settle down.
