What do fleas transmit to cats? - briefly
Fleas can transmit several diseases and parasites to cats, including tapeworms (Dipylidium caninum) and Bartonella henselae, which causes cat-scratch disease in humans.
What do fleas transmit to cats? - in detail
Fleas are notorious for their ability to transmit various diseases and parasites to cats, causing significant discomfort and potential health issues. One of the most common conditions fleas can transmit is flea allergy dermatitis (FAD), which is an allergic reaction to flea saliva. Symptoms include excessive scratching, hair loss, and skin irritation, leading to secondary infections if left untreated.
Another significant concern is tapeworm infestation. Fleas can act as intermediate hosts for tapeworms such as Dipylidium caninum. When cats groom themselves and ingest fleas carrying tapeworm larvae, the larvae develop into adult worms in the cat's intestines. While tapeworm infestation is often asymptomatic, it can cause weight loss, anemia, and gastrointestinal discomfort in severe cases.
Fleas are also known to transmit Bartonella henselae, the bacterium responsible for cat-scratch disease (CSD). Although CSD primarily affects humans who have been scratched or bitten by infected cats, fleas play a crucial role in the transmission of this bacterium between felines. Symptoms in cats may include fever, lethargy, and enlarged lymph nodes, while human symptoms can range from mild flu-like illness to more severe complications.
In addition to these direct transmissions, fleas can exacerbate existing health conditions in cats. For instance, flea bites can cause anemia in kittens and geriatric cats due to the loss of blood, which can be life-threatening if left untreated. Furthermore, fleas can introduce other parasites such as Haemoplasma species, which can lead to feline infectious anemia.
In summary, fleas pose a significant threat to feline health by transmitting diseases and exacerbating existing conditions. Regular flea prevention and control measures are essential for maintaining the well-being of cats.
