Behavioral Effects of Fleas on Cats
Fleas can significantly alter a cat’s behavior. Physical discomfort leads to excessive scratching, biting, restlessness, hair loss, and skin lesions. Cats may groom excessively, become aggressive, hide, lose their appetite, or seem depressed.
Other Effects
Flea allergy dermatitis can cause severe skin reactions. Heavy infestations may cause anemia, especially in kittens, and fleas can transmit tapeworms.
Symptom severity depends on the cat’s sensitivity and infestation level. Consult a veterinarian for diagnosis and treatment.
