Wondering what this could be?

Hello, everyone I have a female kitten that's about 7months old she seems to have developed. A primordial pouch but she hasn't been fixed yet..I know this is common with fixed cats but what about not fixed cats?? Can someone help me out??

It is common. According to what I have read it serves as protection in a fight when a cat gets 'bunny kicked' - keeps the stomach from being severely injured. It is even part of the breed standards for some breeds. One of my whole girls that I show in championship (Persian) has the 'hangey down thingie' (My own technical term for it! ). It is not necessarily just spayed cats that develop it.

Almost all cats develop these, even males, although to a lesser degree. Most do get them when they are older, but it is not unusual for a kitten as young as yours to start.  My poor Chrissy had a large one and everyone always thought she was a nursing mother, I can just see her being very annoyed at this!

Okay so the more that I rub on her belly the more it seems like it's not the pouch it seems more like her breasts I dont know what to call cat boobs. But they seem to be swollen ugh this is hard to explain like all the boobs all the way down to her pouch I hope I made sense lol

You need to fix your cat. Maybe it has something to do with her hormones, which can be all over the place because she's unfixed. Does she frequently howl & writhe on the floor?

No she shows no signs of going into heat yet they feel engorged it's so weird kinda like how some ppls boobs get before their periods or after a baby. She's a sweet and extra loving kitty that is the only thing wrong with her I just noticed it

Sounds like you are dealing with Mammary Hyperplasia. Hormones cause the breasts to swell like they have milk in them and the symptoms mimic mastitis even though the cat isn't nursing kittens. I dealt with this in one of my girls. It can be serious if the skin splits and ulcerates. Best solution is spaying. She will likely be coming into heat soon since this is happening. I would speak with the vet now about spaying her, before it gets worse and is a much more involved (and expensive) surgery.  My girl was fine,even though I did not spay her - she was pregnant with her first litter of kittens (I am a breeder) when she developed it. Poor baby looked like Dolly Parton on steriods! The swelling went down after she had the kittens and we were lucky there was no tearing or ulceration. This sometimes happens to young cats around their first heat, although from what I have read is fairly uncommon.
