Walking dandruff in cats, also referred to as Cheyletiellosis, will actually look like dandruff but there is one caveat; this dandruff moves. It can cause your cats skin to become both scaly as well as flaky, become extremely itchy, and in the most severe of cases it can cause redness which may lead to open sores. What make this skin condition even more dangerous is that it is a zoonotic disease as well.
