Yes, mother cats do mate with their offspring. I had cat which had become so old that my family members used to call her grandmother cat. I had once seen her mating with her offspring and THEIR offspring at different times!
Yes when cats ovulate there is more than one egg released. Depending on her health and heredity the number of eggs released may vary. Any egg can be joined by any sperm. If more than one male added sperm then there could be kittens fathered by different males in the same litter.Cats are induced ovulators-the eggs do not release unless a mating takes place.This increases the chances that if she mates with more than one male eggs could be fertilized by different males.f more than one male added sperm then there could be kittens fathered by different males in the same litter.
