How does scabies appear in cats? - in detail
Scabies in cats, also known as feline scabies or notoedric mange, is caused by the mite Notoedres cati. These mites are highly contagious and can spread rapidly among cats living in close proximity, such as in shelters or multi-cat households. The life cycle of Notoedres cati typically takes about 17 to 23 days from egg to adult mite.
The initial stage of scabies infection in cats is often characterized by intense itching and irritation, which can lead to excessive scratching and grooming. This behavior is a response to the allergic reaction caused by the mites' saliva and feces deposited on the cat's skin. The most commonly affected areas include the head, ears, neck, and sometimes the legs and tail base.
As the infestation progresses, the cat's skin may become red, inflamed, and thickened due to chronic scratching and irritation. Crusts and scabs can form on the skin surface, giving rise to the characteristic appearance of scabies in cats. These crusts are often filled with mites, eggs, and fecal material. In severe cases, the cat may experience hair loss, secondary bacterial infections, and even changes in behavior due to discomfort and distress.
Diagnosis of feline scabies is usually based on the clinical signs observed and the identification of mites or eggs under a microscope following a skin scraping. Treatment typically involves the use of topical insecticides, such as selamectin (Revolution) or imidacloprid/moxidectin (Advocate), which are applied directly to the cat's skin. In some cases, oral medications may also be prescribed.
It is crucial to note that scabies mites can survive off the host for a short period, making environmental decontamination an essential part of treatment and prevention. This includes thoroughly cleaning and disinfecting bedding, litter boxes, and other areas where the cat spends time. Additionally, isolating infected cats from healthy ones is crucial to prevent the spread of the infestation.
In summary, scabies in cats appears as a result of an allergic reaction to mites, leading to intense itching, irritation, and skin changes such as redness, thickening, crusting, and hair loss. Prompt diagnosis and treatment are necessary to alleviate the cat's discomfort and prevent further spread of the infestation.
