Cat with a crusty spot on the body

Cat Skin Lesions

It is a common phenomenon for cats to have crusty spots on their bodies, which are usually caused by fungal infections or ringworm, among other reasons. Additionally, if a cat has suffered trauma, it may also develop crusty lesions. Effective treatment depends on identifying the underlying cause.

What Causes Crusty Spots on Cats?

Possible causes for crusty spots on cats include:

Trauma: This can cause crusting on the cat's skin. It is advised to consult a veterinarian promptly for examination and treatment.
Parasites: This situation also requires timely inspection and deworming treatment at a pet hospital.
Matted fur: This type of crust is not caused by a specific disease but by prolonged neglect. Regular fur brushing is recommended for this condition.

What Medications Should Be Used for Cat Skin Lesions?

If caused by trauma, observation is sufficient. If due to fungal or bacterial infections, common medications include terbinafine spray, terbinafine tablets, fungicidal injection, and topical shampoo baths. The treatment duration is usually over four weeks. Regular fungal testing is necessary after recovery to prevent recurrence. Common pathogens of feline fungal infections include Canine Microsporum, Trichophyton mentagrophytes, Sporothrix schenckii, and Cryptococcosis. Causes include contact transmission and poor living conditions that lead to decreased skin resistance. Clinical symptoms include dryness and itching on the inner sides of limbs, face, and trunk.

Should the Crust Be Removed?

Yes, the crust must be removed and cleaned thoroughly to prevent bacterial infection. Feline ringworm is a skin fungal disease that causes hair loss and itching when it infects a cat. It initially affects only a localized area but can gradually spread to the entire body. When a cat has a crusty lesion, it may indicate severe itching that leads to bleeding from scratching. For trauma-induced lesions, allow them to heal naturally.
