The Arctic fox has been on record as producing the largest litter in the wild animal kingdom. According to Alaska Fish and Game, the Arctic fox has been known to have as many as 15 pups at a time. The average for this animal however is closer to 7 or 8 pups.
With domestic dogs, a litter of puppies can vary in size. However, it is not unusual for one female dog to have ten or twelve puppies at one time. The heat cycle of a female dog can occur every twelve to eighteen months.
Most people are familiar with Canada geese. They are the brownish/grayish colored geese that can be seen virtually everywhere in North America. It is not an exaggeration to put them on this list.
The number of eggs a sea turtle may lay will vary from species to species. The leatherback sea turtle, for instance, the largest of all sea turtles, will lay over 100 eggs per clutch. A female sea turtle may have 2-8 clutches per season.
A female domestic cat can become pregnant as early as five months of age. One female alone can produce upwards of 100 offspring in her life, which can lead to her being directly responsible for as many as 400,000 kittens.
