Yeast infection questions.

I have never had a yeast infection but I’m pretty sure I have one now. I’m not sexually active and I’m itchy down there - specifically my vaginal lips if that makes a difference. With never having a yeast infection before I wonder if that’s even what this would be. It’s only itchy- no foul smell, my discharge doesnt seem abnormal to me? So my first question is opinions on if that’s a yeast infection or not. To go along with that. If it is a yeast infection can I cure it at home? If I do have to see a doctor do they have to look at my 🐱?
