As a cat owner you may have heard rumors that a cat like the American Bobtail can actually get pregnant by multiple male cats. Contrary to popular belief this myth is in fact true. It is possible for a cat like the American Bobtail and other breeds to be impregnated by multiple cats. This is what leads to the various colors and markings of kittens within the same litter. Female cats continue their heat cycle even if they are pregnant. Multiple eggs can be released over the course of a cat’s cycle which can last from three to twenty days. Having multiple “fathers” so to speak is known as superfecundity. Some American Bobtails come into heat between their third and sixth week of pregnancy. Although extremely rare, some cats can carry fetuses of different ages from different mating times (in different heat cycles) through a process known as superfetation.
