Do Cats Have Belly Buttons?

Do cats have belly buttons?

Yes, they do, all mammals have belly buttons (also known as a navel or umbilicus). The cat's belly button is located midway down the abdomen and is a circular scar approximately 5mm in width. It doesn't look the same as the human belly button, the cat's is smooth with a slight indentation in it. The cat's belly button can be somewhat difficult to find, I have three cats and only one has an easily visible belly button. It would appear it is more visible on dark coated cats.

Just like humans, the placenta attaches to the uterine wall of the pregnant cat (known as a queen), with the umbilical cord travelling from the placenta to the fetus. The cat fetus obtains water, nutrients, and oxygen from the mother via the placenta while carrying fetal waste and carbon dioxide away from the fetus.

Each fetus has its own placenta and umbilical cord. So, if there are 4 fetuses, there will be 4 placentas, the only exception to this rule is if two of the fetuses are identical twins, in which case they will share a placenta.

Shortly after the kitten is born, the queen's uterus will begin to contract again and the placenta will be delivered. At this point in time, the kitten is still attached to the placenta and may still be receiving blood and oxygen. One he takes his first breath of air, the queen will bite or lick the cord until it detaches from the kitten, the placenta will be eaten. A short stump will remain attached to the kitten which will slowly dry and shrivel up. By the third day, this stump will fall off.

Umbilical hernias can sometimes occur in cats and are due to an opening in the abdominal muscles which allows the contents of the abdomen to pass through the opening. Signs of an umbilical hernia include umbilical swelling, pain, vomiting, loss of appetite and depression. Surgery is required to correct umbilical hernias.

Umbilical infections can also develop in newborn kittens. Signs of an infected umbilical infection include redness, swelling and oozing pus. This is a potentially life-threatening situation and needs to be treated by a veterinarian urgently.
