ELI5: Why can't cats or dogs recognize their young after awhile and will often times even mate with them?

Often times when a dog or cat has a litter after a year or two of separation the dog or cat has no notion of who it is. Sometimes these animals will even mate with each other. Is there no instinct or evolutionary factor that would enable animals to deter from inbreeding?

It is not that they do not recognize their offspring, it is as you say that there is no instinct to avoid inbreeding. In the wild inbreeding of a population is often the only thing that keeps a species alive in a given area. Particularly if that area is remote or hard to get to.
