I think my cat is growing another toenail? It’s right under her thumb nail. What should I do in this situation? Do I just leave it?

This looks like a cutaneous horn which is a keratin growth from the paw pad. I would consider having this removed and having the growth sent for histopathology as it could be benign or caused by cancerous process.

It is possible your cat has what is called a "cutaneous horn" on her foot, which is an overgrowth of keratin and can look like a claw. If the area isn't bothering a cat we often leave it alone, but if it does cause discomfort then removal is recommended. A vet exam is also recommended to be sure there isn't any other pathology going on in this area, as these can also be seen in cats with feline leukemia or a cancer called squamous cell carcinoma, and we want to be sure there isn't something more concerning going on here.

It's hard to tell from the picture, but you could be seeing an ingrown nail, extra nails that didn't grow right from birth, cutaneous horn, or something else. I would have Pixie examined by a vet to be certain of what is going on.
