I haven’t seen any fleas on her, the skin where the bald spots are seem to be a little raw but I would assume it’s because of her own tongue, when I first got her (2 months ago) she had something similar to really small blisters but they are gone

Thank you guys for your help for a little more info: adopted the cat because she was already in the apartment when I rented it out and the previous owner basically left her here. That’s why I adopted her because I didn’t want her to end up in the street and since she was already in the apartment, she was familiar enough. I decided to keep her, so I don’t think it’s be stress from the home since she was already used to it.
