Otitis Externa is a disease caused by the non-burrowing mite ''[[Otodectes cynotis]]''. It is the most common mite of cats and dogs worldwide and is also seen in foxes and ferrets. The mite feeds on surface tissue in the ear and debris. Pruritus is caused by irritation and the saliva of the mites, which is immunogenic. '''Secondary bacterial infection''' is common, resulting in purulent otitis externa which will require more treatment.

The classical presentation of ''Otodectes'' mite is otitis externa, which affects the external ear canal. In cats, another presentation can be seen, which is that of an ectopic infection where signs are seen on other body parts such as the tail. This is due to contact e.g. cats sleeping in a curled position would allow mites to infest that area.
