Strange crusts, appearing on a domestic cat’s ears, frequently make owners nervous. Some of the most effective pet owners can diagnose a bunch of dangerous animal diseases, such as lichen or scab. But quite often these suggestions are not confirmed by a professional vet. Usually, the creepy crust on a cat’s ears is caused by your pet itself. The matter is that animals by its nature tend to scratch itself pretty frequently. Ironically, this habit makes pet owners even more concerned about their pet health. 

Actually, there are a lot of reasons for crust emerging. But, fortunately or not, chances of that your cat is being infected by lichen are pretty the same as the chances of allergy appearing as a consequence of a wrongly chosen diet. 

Potential Causes of Crust Appearing

Let’s start with identification of what crusts are in fact, and what are the main reasons of its emerging? First of all, crusts consist of clotted blood, bits of pus and necrotic tissue. Reasons of appearing:

  1. Tick or blood sucking insect
  2. Chilblain
  3. Allergic reactions 
  4. Fungal diseases 

It has to be noticed, that if illness can be transmitted to people or to other pets, you have to seek medical attention immediately. For prompt identification of such a contagious illness, turn your attention to animals’ behavior:

  • Cat constantly tilts its head in one direction and furiously itches its own ear trying to get rid of something inside it. Possibly, a tick got into the ear. To check if it’s true, just take a look at the ear canal. Ticks are breeding very fast, so you’ll notice some kind of dark-brown patina inside and crusts outside it. 
  • Flea’s bite always makes the cat itch in an infected zone. Usually, for attack flew choose the most inaccessible zone for animals. Wither, neck, head and ears are the most attractive places to bite for these bloodsucking parasites. 
  • Your country cold? And you have a cat that always wants to go outside for a walk, even if a thermometer shows extremely low numbers? Be prepared for observing some kind of frostbite on its ears. One week later, the damaged area is beginning to heal and the crust appears. By the way, you shouldn’t worry about this so much, because all crust would have gone in a couple of weeks
  • Allergy. Don’t treat your pet with some cheap low-quality products and canned food, which can cause a significant amount of health problems with your cat. A strange itchy rash on the body and white crust on the cat’s ear are the main symptoms of allergy. Your pet just itches so intensively, that tears its skin to a pulp. 
  • Fungal dermatitis disease appearing is a frightening but also realistic scenario. This includes four variations of lichen, scab and other types of dermatomycoses. Actually, symptoms are common for most fungal diseases. Your cat faces problems like fur’s color tarnishing, skin peeling or nasty odor. Furthermore, symptoms like purulent wounds and blisters may cause an appearing of crusts all over the cat’s body. 

Firstly, take a closer look on cat’s skin – if there are any crusts not only on ears, we strongly recommend you to take a visit to the vet as soon as you can.
