Why don't dogs and cats have belly buttons?

Question

We, as humans have belly buttons, where the umbilical cord was cut and healed in a weird innie or outie way.

But examine the belly of a dog or a cat and you'll be (possibly) surprized to see that it doesn't have a belly button.

As they are born with an umbilical cord, just like us, how come they don't end up with a belly button, just like us?

Answer 1

its something to with them bieng a sac in the womb and i dont think they have umbilical cords

Answer 2

ALL placental mammals have belly buttons because they are all connected to the mother via an umbilical cord in the womb.

Those on dogs & cats are very hard to see because they heal realy tightly.

Answer 3

how strange! ive never noticed this before,, now you mention it, they havent lol...hmm.. i dont no they must not have umbilical cords?!?

Answer 4

Cats and dogs do have a spot where their umbilical cord was once attached, it's just very hard to see.

Answer 5

All Mammals, except for the Monotremes, have belly buttons.  Some are not as visible as others because they've healed so well, but they all have them, even Whales and Dolphins.
