What disease causes a cat to scratch its ear? - in detail

Ear mites, also known as Otodectes cynotis, are tiny parasites that commonly infest cats' ears, leading to persistent scratching and discomfort. These mites are highly contagious and can be transmitted between cats through direct contact or shared bedding. The presence of ear mites often results in a dark brown or black crusty discharge from the ear canal, which may appear as coffee grounds. Additionally, affected cats may exhibit head shaking, ear odor, and redness or swelling inside the ear. If left untreated, ear mite infestations can cause significant discomfort and potentially lead to secondary infections. Veterinary treatment typically involves a combination of cleaning the ears with a suitable solution and applying topical medications specifically designed to eliminate the mites. Early detection and prompt intervention are crucial for preventing complications and ensuring the cat's well-being.
