What are Skin Ulcers?

Skin ulcers in cats are defects in the surface layers of a feline’s skin. The ulceration is often slow to heal, requiring careful observation and veterinary care. The majority of skin ulcers are the result of trauma from an outside source, but can also be linked to certain varieties of disease.

If you notice a crusted wound on your cat’s foot, nose, or skin, it is likely that she has a skin ulcer. Skin ulcers in cats can be a red, inflamed sore spot on the cat’s skin, or the wound can open, seeping discharge from the affected area. Feline skin ulcers have many possible causes including parasites, infections, allergies, disease, burns, and a variety of other skin irritants. Cats also have a tendency to self-manipulate a wound, licking or biting continuously until the skin problem becomes severe.

Symptoms of Skin Ulcers in Cats

The initial signs of skin ulcers in cats is a crusted area of the feline’s foot, nose or skin. As the ulceration progresses, or if the cat has inflicted self-manipulation, the skin problem can progress into an extensive lesion. The affected area may open, draining a thick, white substance, the area around the ulcer may become red and irritated, and the cat may lose hair in the area.

Diagnosis of Skin Ulcers in Cats

Skin ulcers in a cat takes a timely differential diagnosis, as this skin condition can be caused by numerous conditions. Diagnosis of a skin ulcers in cats will require a review of the cat’s medical history, plus a great deal of communication between the pet owner and the veterinarian. Pet owners will be required to tell the veterinarian when the ulcer was first noted, where the cat spends most of her time and what the pet owner suspects could be the cause of the skin problem. In order to make an accurate diagnosis, the veterinarian may choose to perform a variety of diagnostic tests including:

  • Skin cultures: swabbing the skin and examining the sample will determine if the ulceration is caused by an infection of bacteria, or fungus. 
  • Aspiration of Fluids: Syphoning a small sample of the draining fluids can be used to determine possible caused when examined under a microscope.  
  • Skin biopsy: a portion of the surrounding tissue may be removed to be examined in a laboratory setting.

Treatment of Skin Ulcers in Cats

Treatment of skin ulcers in cats vary depending on the underlying cause of the skin condition. Your veterinarian will tailor a treatment plan to your cat’s specific condition and overall health. The majority of felines can receive treatments at home as an outpatient, but if your cat requires supportive care, she may be required to stay in the clinic for a few days. An Elizabethan collar is often sent home with patients to prevent the cat from licking, biting or scratching at the ulceration, making the problem worse. Pain medications, anti-inflammatory drugs, antibiotics and antifungal medications are just a few medical options your veterinarian may recommend to your cat with a skin ulceration.

Recovery of Skin Ulcers in Cats

The prognosis of skin ulcers in cats depends on the underlying condition that caused the feline’s skin to ulcerate. Follow-up care with your veterinarian is highly important to ensure the wound is healing and the therapeutic treatments are working as planned.

Thank you for your question. I apologize for the delay in answering, this platform is not set up for urgent emails. From your picture, that appears to be a bacterial infection, and may need antibiotics or other medication to help keep it from getting worse. It would be best to have them seen by a veterinarian, as they can examine your pet and see what might be causing this, and let you know what treatment might help.

Open Sore

Our farm cat has come up with a wound near his ear, which was smaller but now has grown in size. Wondering if we can use a topical anti bacterial ointment and a cone to stop from itching or clawing at it more.

Thank you for your question. Cats can get really nasty infections of their skin or parasites in the ears that can be intensely itchy and cause problems. I'm not sure that a topical medication is going to be enough in this situation, and I think putting a cone on while he is itchy is sort of torture. I think it would be best to have him seen by a veterinarian, as they can get to the bottom of the problem and treat him so that he feels better. I hope that he is okay.

Red Sore/Scab

My cat has a scab patch on her stomach, but no injury that I'm aware of her getting. It doesn't seem to bother her, but it doesn't seem to be healing. I'm wondering if a cone collar would be sufficient to just let her leave it alone long enough to heal or if I should take her in? It's not scabbed over right now because she just licked it

Thank you for your question. If she is licking it and not letting it heal, then it probably is bothering her. You can try cleaning the area twice daily with a chlorhexidine solution like Hibiclens, and see if that helps it heal. If she continues to lick at it, or it isn't healing, it would be better to have her seen by a veterinarian to figure out what is causing the lesion so that she can get medication to help. I hope that all goes well for her.

Itching, Hair Lose

My 18-month-old Bengal cat was bitten by a mosquito and had an allergic reaction. He has a dime size area on his forehead and after two weeks, he has stopped scratching the area and has cleaned the dead shin and scab away. The area is now a dried pink area. Will his fur return as the skin continues to heal. I am getting medication from the vet in the morning to help with any itching he may have. He is a show quality cat, but I choose not to enter him in shows.
