Cat Ringworm Treatment: Effective Injections for Feline

Cat ringworm is typically not treated with injections; instead, topical medications or oral treatments are usually sufficient for a cure. Ringworm in cats is a common skin condition caused by fungal infections, affecting nearly 90% of catowning households at least once. Many new pet owners might be unsure of how to treat it when their cat contracts ringworm. Today, I'll provide a detailed guide to help you understand and manage this condition.

Section 1: Causes of Ringworm in Cats

Ringworm in cats is primarily caused by fungi such as Microsporum canis, Trichophyton mentagrophytes, and Microsporum gypseum, with Microsporum canis being responsible for over 90% of cases.

This zoonotic fungus is commonly carried by both cats and dogs. However, when a cat's skin resistance is strong, the fungus usually doesn't cause any issues. But if a cat's immune system is weakened, the skin barrier is compromised, or it comes into direct contact with a high concentration of the pathogen, ringworm symptoms may arise.

Section 2: Symptoms of Ringworm in Cats

Cats with ringworm may exhibit the following symptoms:

Round patches on the skin, which may have脱毛 (hair loss) around the edges;

Redness and swelling of the affected area, sometimes accompanied by scales;

In some cases, cats may excessively lick the affected area due to itching;

In severe instances, the infected area may expand and lead to more widespread skin issues.

Section 3: Diagnosing Ringworm in Cats

If you suspect your cat has ringworm, you can use a Wood's lamp to check for green fluorescence, which is a reaction to the metabolic products of some Microsporum canis under ultraviolet light.

For a more accurate diagnosis, it's best to visit a veterinary clinic where a skin scrape test or fungal culture can be performed to confirm the presence and type of the fungus.

Section 4: Treating Ringworm in Cats

Once ringworm is confirmed, treatment can begin. The treatment plan usually involves the following aspects:

For localized infections, apply antifungal topical treatments like Daktarin (ketоконазол cream) or Pimafucin (tолнафен hydrochloride spray) to the affected area twice or thrice daily. Before applying, trim the hair around the affected area and clean it with iodine to remove scales, crusts, and dust.

For widespread infections, cats with severe ringworm may require a combination of oral medication and medicated baths. Oral medication often includes itraconazole, taken once daily at a dose of 5 to 10 mg/kg, for a week followed by a week off. For medicated baths, consider using a 2 to 4% lime sulfur solution, applied once or twice a week.

Important Considerations:

Fit your cat with an Elizabethan collar to prevent it from licking the affected area;

Ensure environmental disinfection to prevent the spread of the fungus or recurring infections;

Supplement with B vitamins and fish oil to aid in skin repair;

Expose your cat to sunlight to help kill bacteria and boost skin immunity.

In summary, ringworm in cats usually doesn't require injections. Treatment typically involves topical medications, medicated baths, or oral medications, depending on the severity of the condition. Avoid overloading your cat with medications to prevent adverse reactions.
