Treatment :

Credelio every month .

After seconde credelio the cat was adopted in Germany so we don’t see her in the end of treatment ,but the ownrs says that her skin is perfect now .

Conclusions :

Demodecosis is cats is less common compare to dogs ,but always have to be in diferentilas in cats with pruritus and waxy ears .

It could be with very pleomorphic clinic and always should be performed deep skin scrapyng if we suspect  demodecosis .
