My cat's ear smells bad and drains black stuff. Is it dangerous?

Pet's info: Cat | Norwegian Forest Cat | Male | neutered | 3 years and 9 months old | 20 lbs

My cat has a bad ear mite infestation. His ear collapsed about 2 months ago, it swelled up but a week ago the swelling was gone. It started draining black stuff, now there's an odor but still no swelling and no redness, just smells. Please help. I can't afford a vet until the middle of July. Is he in danger?

You really can't appreciate anything of significance from the photo unfortunately; however, based on your description it sounds like your cat may have had an aural hematoma (blood filling of the ear pinna due to a rupture vessel in the ear). This is usually a sequela of an ear infection, or as you suspect, a mite infestation. You may be able to find ear mite medication over the counter at your local pet store or online. However it sounds like the ear may also have a bacterial infection as well (due to the odor that you are smelling). Your pet is at risk for having permanent hearing loss and/or an inner ear infection which can cause some neurological abnormalities (head tilting) if this is not treated quickly. I would suggest perhaps one of the financial resources below to help you get Yogi seen earlier than mid July. www.carecredit.com redrover.org I hope that everything works out well for your cat Yogi and that he is able to make a a full and speedy recovery.
