Is it even a corn snake?

It appears to be the same snake to me. If you look at the second adult picture, you can see the same patterning. Certain snakes change (fade) pattern and color as they mature; most Rat snakes do.

I'd say it's either a Yellow Rat or a hybrid Yellow Rat.

I see a lot of what appears to be feces in that cage too.

I do see what your saying, the saddles are still there in the later pics, but very light. Just barely discernible in this pic.
