How long does it take for a kittens umbilical corn to fall off?

Typically, a kitten's umbilical cord will fall off within 1-3 weeks after birth. The umbilical cord is the connection between the mother and the kitten during pregnancy, and it provides nutrients and oxygen to the kitten. After birth, the umbilical cord is no longer needed, and it will gradually dry up and fall off. If the umbilical cord does not fall off within 3 weeks, you should take your kitten to the vet to have it checked.
