Fleas are small, wingless parasites that feed on the blood of cats and other animals. They can cause itching and skin problems and may also transmit other parasites, including tapeworms.
Fleas have four stages in their life cycle: egg, larva, pupa and adult. Most of the flea life cycle takes place in the environment rather than on your cat, which is why treating your cat alone may not be enough to clear an infestation.
Itchiness and skin problems: persistent itching, skin infections and hair loss. Some cats develop flea allergy dermatitis, which is the most common skin disease in cats.
Anaemia: fleas suck blood, leading to anaemia, especially in young or old cats. Severe cases can be lethal.
Parasite transmission: fleas can carry tapeworms that infect cats, causing anal itching and nutrient loss.
If you notice any fleas on your pet or any of the above symptoms, contact your local practice.
Diagnosis involves identifying adult fleas or fleas' dirt on the pet’s coat, or signs of flea allergy such as redness, bold patches and itchiness around the back of the pet and the base of their tail and the back of thighs.
Use of medical products prescribed by a vet will kill fleas on the cat, as well as use of products to spray the home.
Washing all bedding material in hot water and vacuuming the house.
Preventing fleas is simple with year-round use of vet-prescribed products. Understanding the flea life cycle and committing to a prolonged treatment plan is crucial for effectively managing and preventing infestations.
Flea infestations can be treated, but it may take some time to fully resolve. Once the fleas are gone, it’s essential to use preventative measures to keep them from coming back.
