Flea Allergic Dermatitis

We took my cat in to get spayed, they shaved her fur ready to operate and found her skin was very irritated from flea bites which we didn’t previously notice because of her black fur.

We’ve recently moved back to my parent’s house and their cat is friends with a stray who almost certainly, carries fleas. Her skin has gotten better on the patch that was shaved at the vets, but she’s started loosing fur between her legs, her lower back and has some red patches on her neck.

We keep treating her and the house for fleas, and we’re moving house again at the end of the week, so hopefully after deep cleaning everything we’re bringing with us, and bathing the cats, the fleas will be gone.

Does anyone have any recommendations for ointments, vitamins or other treatments that can help with her skin after we’ve gotten rid of the fleas? Any suggestions will be such a big help, thanks so much!
