Cat fleas help!!

Hey everyone, I recently adopted a 3 year old cat. She’s been great but instantly I noticed that she itches a lot.

When I asked her previous owner they said the other cats they owned had no fleas. I am looking into getting the capstar oral flea treatment and the advantage topical treatment. Washing all sheets and pillows she’s been in contact with.

But this is my first hiccup with her and I am kinda freaking out. Should I be doing anything else?

Any advice would be really helpful and appreciated. Thanks everyone.
