What Causes Cats to Itch With Scabs on the Skin?

Many scenarios may cause a cat it scratch to the point of causing scabs. Though itchiness and scabs are common symptoms, other symptoms can help you pinpoint the cause of feline skin problems. Skin problems that lead to scabbing range from parasites to food and airborne allergens.

  1. Fleas

    • Scabs and itchiness may indicate flea infestation. In addition to those two symptoms, you notice flaky and irritated skin. Flea infestations cause hair loss along the back, legs and tail. Another telltale sign of fleas is dirt trails along the tail that resemble black dandruff, according to PetSmart.com. A flea bath specially designed for cats can get rid of the existing fleas. Never use insecticides designed for dogs on cats. This may cause an extremely toxic reaction.

    Mites

    • Mites cause a condition known as feline scabies. This normally manifests as hair loss and itching centered on the face. Yellow or gray scabs characterize feline scabies. Mites only live on cats a few days. In this period, cats may develop a secondary infection because of extreme scratching. The first step to get rid of mites is to shampoo the cat. According to AnimalPlanet.com, a dip containing between 2 and 3 percent lime sulfur should be applied after the shampoo to remove and kill mites.

    Allergies

    • PetEducation.com estimates that 57 percent of itchiness in cats can be attributed to food allergies. Cats may also develop allergies to pollen, fleas, smoke and fabrics. Itchiness and scabbing are just two of many symptoms. You may notice that your cat's paws may be swollen. The cat can also develop gastrointestinal symptoms such as vomiting and diarrhea. Respiratory symptoms like sneezing, coughing and snoring are also common. A veterinarian can help you narrow down potential allergens. Your veterinarian may suggest shampoos or sprays to relieve and prevent skin problems.

    Ringworm

    • A fungal infection, ringworm often infects a cat's skin. Cats can carry the fungi that cause ringworm for as long as two years. Ringworm infects cats when their immune system is depressed. Kittens, senior cats, and cats with diseases or infections are likely to become infected. Ringworm shows up as a round hairless spot. The spot may be scaly with small pimple-like lumps. Ringworm can appear on any part of a cat's body, but the scratching typically begins around the ears. Ringworm is typically treated with a topical antifungal cream. Your veterinarian may also prescribe oral antifungals for severe conditions.
