Cat fascinated with the bellybutton of their pregnant owner

The title to this Reddit.com video is "Cat realises owner is pregnant". But when you watch the video you see this charming cat primarily interested in the smell of this pregnant woman. And it seems to me that this cat is particularly fascinated with the smell emanating from the woman's bellybutton. That's the central object in the short video. 

We are not sure why this cat is so fascinated with that aspect of this woman's anatomy. It must be the smell. And perhaps the smell is linked to the woman's pregnancy. Does a woman smell differently when they are pregnant? I'm sure they do.

Well perhaps, I am not be so sure. Although a woman's sense of smell apparently improves when they are pregnant. This may account for the belief that they feel that "stink". This does not explain why this cat is particularly fascinated with this smell of her bellybutton.

It seems that it is not uncommon for a cat to sniff a woman's bellybutton. On the BabyCenter.com website a visitor said: "My cat sniffs my bellybutton but only since I've been pregnant. It's the strangest thing."

And in response to that comment, another woman said that cats know [when you're pregnant]. This woman is convinced that dogs know as well. Her dog puts her ears up against her belly to listen to the baby. And another member of this website says that her cat has been trying to lay on her belly since she got pregnant. She prevents it happening because it is uncomfortable.

And yet another says that animals know when you're pregnant. One pregnant woman said: "My cat hasn't left me alone since around the time I found out! He constantly wants to be on me or at least next to me with his head resting on my belly or some part of him touching me LMAO! "

She let him do it because she loves him to death. Her husband is deployed she said. I presume that means that her husband is in the military and is deployed to another place for a certain time. Therefore it's nice for her to have "a little extra attention sometimes, even if it is from the cat ha ha!"

The big questions are: do cats know when their owner is pregnant? And what does the smell of a pregnant woman say about her to a cat? Does it tell the cat that she is pregnant? Or that she has change in some way? We know that cats identify others by their body odour. I am sure that cats recognise the change in a pregnant woman. It is a mystery what it means to a cat.
