What diseases in cats cause itching? - briefly
Cats may experience itching due to conditions such as flea infestations, allergies, ringworm, or mange caused by mites. Skin infections, autoimmune diseases, and dietary sensitivities can also trigger itching in felines.
What diseases in cats cause itching? - in detail
Itching in cats, known medically as pruritus, can be caused by a variety of diseases and conditions, each with distinct underlying mechanisms. One of the most common causes is flea allergy dermatitis, where cats develop an allergic reaction to flea saliva, leading to intense itching, redness, and skin lesions, particularly around the base of the tail and hindquarters. Environmental allergies, such as atopic dermatitis, can also trigger itching due to hypersensitivity to airborne allergens like pollen, dust mites, or mold. Food allergies are another significant contributor, often resulting from proteins or additives in the diet, causing generalized itching, gastrointestinal upset, and skin inflammation. Parasitic infestations, including mites like Sarcoptes scabiei (scabies) or Cheyletiella (walking dandruff), can cause severe itching and scaling of the skin. Bacterial or fungal infections, such as those caused by Staphylococcus or Malassezia, can exacerbate itching, especially in areas with underlying inflammation or compromised skin barriers. Autoimmune diseases like pemphigus foliaceus, where the immune system attacks the skin, can lead to crusting, pustules, and itching. Hormonal imbalances, such as hyperthyroidism or Cushing’s disease, may also manifest with skin changes and pruritus. Additionally, psychogenic alopecia, a behavioral condition where cats excessively groom due to stress or anxiety, can mimic itching and lead to hair loss and skin irritation. Identifying the specific cause of itching in cats requires a thorough veterinary evaluation, including skin scrapings, allergy testing, blood work, and dietary trials, to ensure appropriate and effective treatment.
