Facts For every person who is born, fifteen dogs and forty-five cats are also born. Millions upon millions of homeless animals are brought into animal shelters each year, and many of them never find a home. A female dog can start having puppies at the age of 6 months and can have two litters a year.
Female cats can start having kittens at the same age, but can have more litters per year.
