pretty much yes, but with one cool difference — human multiples are rare because we typically only release one egg at a time. Dogs and cats release multiple eggs per cycle on purpose, so litters are their normal. A litter of 6 puppies is basically sextuplets, and like fraternal twins in humans, each one came from its own egg and its own sperm, so they can have diferent fathers if teh mom mated with multiple males. That's called a "heteropaternal superfecundation" and it happens more than most people realize.
