Causes of Feline âMangeâ. As described above, mange in companion cats is caused by localized or generalized infestation by external parasites â most commonly Notoedres cati, Cheyletiella blakei and Otodectes cynotis. Cats develop disease by contact with infected symptomatic or sometimes asymptomatic carrier cats.
In this article. Mange is a skin disease caused by several species of tiny mites, common external parasites found in companion canines. Some mange mites are normal residents of your dog âs skin and hair follicles, while others are not. All mites can cause mild to severe skin infections if they proliferate.here are three types of demodectic mange that affect canines.
