Ethical considerations preclude definitive research on the subject, but its safe to say that human DNA has become so different from that of other animals that interbreeding would likely be impossible. After that, those new cells may just sit there, perhaps forever, a permanent part of the partners throat, liver, or whatever else. The different dogs are the same species. The breeding season for cats typically runs from late winter to early fall.
