Of course. The people saying it doesn't happen really need to research cats a little more.

An unaltered female cat who is allowed to roam around when in heat will most likely have a litter of kittens fathered by different toms. Sometimes more than two. Cats are spontaneous ovulators. After the male has ejaculated, he pulls out, and small barbs on the end of his penis rake the vaginal walls inside the female cat which stimulates her to release an egg. Pregnancy rarely results after the first mating which is why females wander around mating whenever and wherever they can. They will continue to do so until their bodies register fertilization which can take long enough for her to have mated several times with several different toms. If the fertilization is from the first or second mating, it's possible for her to have been fertilized by quite a few subsequent males afterwards, resulting in several kittens....sometimes there are litters where EACH kitten has a different father.

Despite what people think, kittens are not "twins" just because they are from the same litter. It IS possible for a cat to have twin kittens, however. If a cat mates with a tom and releases two eggs at once that are both fertilized by that male's sperm....OR if the egg that was fertilized by one male's sperm splits.

And the girl who said her cat was "raped".....give me a break. Cats fight when they mate. This is because the act of mating is not exactly a pleasurable experience for many mammals. In fact, humans and dolphins are the only mammals that have sex for pleasure. For cats and dogs, mating can be a painful experience. If the female had not wanted to mate, it wouldn't have happened.
