What do cats do when they have fleas? - briefly
Cats respond to flea infestations by scratching, biting, and grooming excessively to alleviate itching, often showing restlessness and frequent licking of affected areas. They may also seek relief by rolling on surfaces and displaying heightened agitation.
What do cats do when they have fleas? - in detail
Cats experiencing a flea infestation display several observable reactions. Immediate grooming intensifies; the animal scratches vigorously with hind limbs, attempts to bite at irritated spots, and may rub against furniture or walls to alleviate discomfort. Skin irritation manifests as small red papules or crusted areas, especially around the neck, base of the tail, and belly. Excessive licking can lead to hair loss and open lesions.
Physiological signs often accompany the behavioral responses. Elevated heart rate and increased respiratory effort occur during periods of intense scratching. Appetite may decline, and the cat can become more restless, pacing or vocalizing more frequently. In severe cases, secondary bacterial infections develop at bite sites, producing pus or foul odor.
Typical patterns of activity include:
- Frequent, rapid paw strokes directed at the dorsal neck and tail base.
- Persistent head tilting to reach hard‑to‑reach areas.
- Rolling on the floor to expose the underside of the body.
- Sudden bursts of energy followed by short rests, reflecting discomfort‑driven agitation.
If the cat’s coat appears dull, with visible flea debris (flea dirt) or live insects moving through the fur, the infestation is likely moderate to heavy. The animal’s response may shift toward more defensive postures, such as arching the back and hissing when approached, indicating heightened irritation.
Overall, a flea‑infested cat reacts with heightened grooming, aggressive scratching, localized skin changes, and altered activity levels, all driven by the parasite’s bite and the ensuing allergic reaction.
