How does a cat behave when infected with fleas? - in detail
A cat experiencing a flea infestation exhibits several observable signs that differ from its normal behavior.
Increased grooming is the most immediate response; the animal will scratch, bite, or lick affected areas more frequently, especially around the neck, base of the tail, and abdomen. This heightened activity often leads to hair loss, skin abrasions, and redness.
Restlessness accompanies the irritation. The cat may pace, jump onto furniture, or change sleeping spots in an attempt to find relief. Episodes of rapid, short bursts of movement—often termed “flea frenzy”—are common when the insects are actively feeding.
Appetite may decline. Discomfort and stress can reduce food intake, sometimes resulting in weight loss if the infestation persists.
Behavioral changes in social interaction are also evident. An infested cat may become more withdrawn, avoiding contact with humans or other animals, or conversely, it may seek constant attention to receive soothing petting.
Physiological responses can manifest as:
- Dermatitis: Red, inflamed patches where fleas bite.
- Alleviated after treatment: Reduction in scratching and grooming within 24‑48 hours of effective flea control.
- Potential anemia: In severe cases, especially with heavy infestations, the cat may exhibit lethargy, pale gums, and reduced stamina due to blood loss.
Monitoring these behaviors enables early detection and prompt intervention, preventing secondary infections and long‑term health complications.
