Raccoon breed in the month of January and sometimes even as late as May or June. This can depend of the region of the United States. Their gestation period is about 60-64 days. Most litters are born in April and May, but some may be born later depending on the breeding. There is only one litter of young born each year. They can have one to six, but the average size litter is between three and five. To find out more, have a look at our Animal Facts.
