Not only humans have umbilical cord, all the mammals of the Eutheria infraclass have it, this are the placental mammals and are all the animals that give birth to a live animal but not including the marsupials such as the kangaroo, for example the human, the dog, the cow all have umbilical cord
No not all animals have umbilical cords because not all animals have bellybuttons. For example, any animal that was born from an egg doesn't have a belly button so it didn't have a umbilical cord.
Yes, but the mother will usually bite it off at birth.
Umbilical cords are a development in mammals. Fish, amphibians, turtles, reptiles, and birds would (and all invertebrates) would lack such a feature, as they hatch from an egg.

Yes, they do. When they are born, the momma cat chews through the umbilical cord, and the sack that each kitten is in.

Umbilical cords have two arteries and a vein inside them. These are surrounded by a material called Wharton's Jelly and a protective membrane known as the amnion.
Embryonic stem cells come from umbilical cords in small quantities, which are harvested by collecting cord blood.
They are placental mammals.
No
Two umbilical cords, two placentas, two bags of water, two of everything! That is unless they are conjoined twins.
They get nutrients through their umbilical cords.
A belly button is created by an umbilical cord, so all placental mammals have an umbilical cord. Animals that are hatched would not have an umbilical cord and not have an belly button.
Male adults doesn't have umbilical cords. They are cut off from the placenta when they are born.
