I didn’t sleep much last night, which probably explains the strangeness of these questions:
Is it possible to surgically remove one’s navel? Has it ever been done? Why?
How about adding an extra one?
Here’s my lame question:
Why do we have navels but dogs and cats don’t? Is there another species out there that has belly buttons just like us?
Will work for sig line.
My friend who at one time weighed in over 800 lbs and is currently around 275 is having a surgery to remove the excess skin. In so doing he will lose his belly button. He can have one surgically put back in, but that is all cosmetic. I am just looking forward to tanning his skin and making him a vest a la concentration camp. It will be the newest fad in human clothing. 
HUGS!

They do, but they’re much smaller than ours. They look like tiny scars, not the innie/outie design that we have.
All mammals except the egg-laying type have navels.
And since they don’t wear clothes, they don’t have belly-button lint, either. 
As it happens, this question was addressed in Cecil’s first column.
Alfred Hitchcock didn’t have a navel; it was lost in surgery. There you go.
Well I must say that after reading Cecil’s column I was not satisfied.
Shouldn’t his sentence read “Virtually all mammals except monotremes have belly buttons”? Monotremes being the mammals that lay eggs, e.g. the echidna or the duckbill platypus.
In fact I’m tempted to post this in “comments on Cecil’s columns.”

Does anyone know if any other animals besides mammals have navels? I know there are some snakes and fish that have live births, but I had always assumed that the internal development process was different than it is for mammals. However, they must be getting prenatal nutrients somehow. Do they have something like a placenta, or do they just develop in eggs that “hatch” before birth or something like that?
The only creatures with umbilical cords are mammals. The other creatures that have “live” births, as in some species of snakes, actually have eggs without shells that “hatch” before birth.
