My cat's fur is falling out, skin red & infected. Hotspots or mange?

Updated On September 23rd, 2025

Pet's info: Cat | Singapura | Female | spayed | 13 years old | 6 lbs

She comes to eat in the early mornings, I don't see her for a week or so. About a week ago I saw her with a serious problem on her skin where her fur is falling out and her skin is extremely red and infected. I cleaned her with flea shampoo, clean her wounds with peroxide, and started putting ring worm lotion on the areas. It is spreading all over her and i will take her to the vet on Monday but still wanted to ask here.

Poor Taba! These look like severe hotspots which are ulcerated area caused from excessive scratching. She likely is having a bad reaction to fleas, allergies, or it could have just been a small wound that has progressed due to her messing with them. This could also be secondary to mange. It doesn’t look like typical ringworm which is usually really crusty. I would put a little neosporin on those areas and if she will let you, put a cone collar on her to prevent her from licking/scratching those areas. I would also try to confine her to an area so the cone collar doesn’t get hung up somewhere and so the wounds stay clean. I would not use hydrogen peroxide again as it will slow healing if used continuously. You can try giving her Benadryl to help reduce the itching. See link below. Your vet will be able to get her a steroid shot and antibiotics to help these area heal. Your vet will also be able to look for the cause and see if she needs to be on a high quality flea preventative or other long term allergy meds. I hope this helps and she starts to feel better soon! https://www.petcoach.co/canigive/cat/benadryl/
