Excessive Grooming and Fur Loss in Cats

Common Causes

Medical Conditions

• Allergies: This is a very common cause. Cats can be allergic to environmental factors (pollen, dust mites), food ingredients, or flea bites (Flea Allergy Dermatitis - FAD). The intense itchiness leads to excessive licking, chewing, and grooming, resulting in hair loss, especially over the lower back, inner thighs, and abdomen.
• Parasites: Fleas, mites (e.g., notoedric mange, Cheyletiella mites), and lice can cause intense itching, leading the cat to over-groom the affected areas.
• Fungal Infections: Ringworm (dermatophytosis) is a common fungal infection that can cause patchy hair loss and itchiness.
• Pain: Localized pain, such as from arthritis, a bladder infection, or an injury, can cause a cat to excessively lick the painful area. For instance, cats with bladder issues might over-groom their abdomen.
• Endocrine Disorders: Less common in cats compared to dogs, but conditions like hyperthyroidism can sometimes cause changes in skin and coat health.

Behavioral/Psychological Factors

• Stress or Anxiety: Just like humans might bite their nails, stressed or anxious cats can over-groom as a coping mechanism. This can be triggered by changes in the home environment, new pets, conflicts with other animals, or a lack of mental stimulation. This is often termed
