What is Dust Mite Allergy?

Dust mites live in the home of pet owners, residing in cloth toys, upholstery, mattresses, bedding and carpeting. These mites thrive in humid temperatures, specifically the hot air exhaled during times of sleep. Dust mites feed on skin cells, environmental viruses, fungi and bacteria, but prefer the skin scales of atopic felines. Although the mites may feed on dead skin cells, the actual mite does not cause an allergic response, but rather the dust mite feces. Dust mites have a specialized protein, Der p1, which is passed in their feces and causes a feline to become hyper allergenic. An affected feline may have asthma-like symptoms, such as coughing or wheezing, paired with pruritus, hair loss and skin lesions.

Dust mites allergies in cats is a non-seasonal, allergic response to the microscopic mite commonly known as the dust mite. Dust mites are one of the most common causes of feline allergies with a surprising 30 to 80 percent of all atopic pet cases tested revealing a positive result for dust mites. The United States is home to two species of dust mites: Dermatophagoides farinae and Dermatophagoides pteronyssinus, however, Dermatophagoides pteronyssinus is more common to the United Kingdom.

Symptoms of Dust Mite Allergy in Cats

A feline suffering from dust mite allergies may experience recurrent seborrhea, otitis (ear itching and inflammation), pyodermas (skin infections) and generalized pruritus, specifically on the feet or face. A feline may also show clinical signs of eosinophilic granuloma complex lesions, plasma cell pododermatitis, or chin acne. Dust mite allergies in cats will also cause symptoms including: 

  • Crusty skin patches
  • Hot spots
  • Localized hair loss 
  • Skin damage 
  • Scratching 
  • Itching 

Secondary to skin reactions of dust mites, your cat may also develop a form of allergy-related asthma. As the feline inhales the fecal dust from the mites, he or she may cough or gag, and do so in a hunched posture in an attempt to stabilize breathing.

Causes of Dust Mite Allergy in Cats

Dust mite allergies in cats is caused by the Der p1 specialized protein found in the mites’ feces. Coming into contact with said fecal particle, the feline’s immune system overreacts, creating antibodies for the antigen. Dust mites allergies are non-seasonal, but felines may develop an allergenic condition during the fall and winter months. Likewise, an outdoor cat that is brought indoors during the cold months of the year may suddenly develop an allergy as the home is closed up, keeping the dust mites in a confined area.

Diagnosis of Dust Mite Allergy in Cats

The diagnostic tests specific to dust mite allergies is the skin sensitivity test or the serum IgE test for the reaction to Der p1 proteins caused by dust mites. However, other mites, such as the Cheyletiella, Otodectes and Sarcoptes mite, belong to the same order of acarids, therefore, false positives can occur. For example, if your feline has Cheyletiella, she could actually test positive for dust mites too. Your veterinarian will then use your feline’s clinical symptoms to differentiate between the types of mites and retest the feline. The symptoms associated with dust mite allergies in cats mimic those of food allergies, seasonal allergies, environmental allergies and a number of infections, so a differential diagnosis will need to be made. A differential diagnosis may include a skin scraping, skin cell cytology, skin sample culture and blood test.

Treatment of Dust Mite Allergy in Cats

Dust mites allergies in cats are treated with immunotherapy and changes in the environment. Subcutaneous or sublingual administration of cyclosporine corticosteroid drugs is the norm for immunotherapy treatment prescribed by veterinarians for feline dust mite allergies. However, the most important portion of the treatment plan is treating dust mites at home. Vacuuming and cleaning carpets once a week, dusting in combination with routine sweeping will eliminate allergy causing dust mite feces in the home. Cat owners are advised to wash all cat bedding and their own bedding if the feline sleeps in bed with their owners. The washing of bedding can take place once a week in combination with sweeping, dusting and vacuuming.

Recovery of Dust Mite Allergy in Cats

Felines generally respond very well to immunotherapy treatments, but in order to prevent a recurrence, pet owners must keep a clean home. Changing the air filters in your home heating and cooling system can greatly reduce dust mite allergens in the air. Pet owners can also wash their bedding with tea tree oil or steam clean their mattresses, as studies show these methods result in an even higher elimination rate than regular cleaning. There is also a varieties of hypoallergenic pillow cases and bedding available that are said to discourage dust mites.

Thank you for your question. Your cat may have a viral flare up, or dust may be irritating his eyes. If things do not improve over the next day or two, It would be best to have your pet seen by a veterinarian, as they can examine them and see what might be going on, and get any treatment needed.

Inflammation In Face/Mouth

Hi there. My cat has been diagnosed with eosinophilic granuloma complex (hopefully I’m spelling that right) and we’ve already done food trials and flea collar treatments to deal with his face inflammation. Is it possible that dust mites could be the underlying allergy? I have interior brick walls and I thought maybe this could be the cause. The next step for him at the vet is a medicine for his allergies which costs way too much. If I can isolate the cause of his allergy I could potentially save me and him a lot of trouble. His face is clear right now -vet gave him short term steroids. Are dust mites in the brick wall a potential cause?

Dust mites have been indicated as a cause in some literature but I cannot say whether this is the case here; one option is to move Weasley to someone else's home for a few weeks to see if there is any improvement in symptoms to isolate whether it is something in your home which is triggering this condition.

I have had Toby for a little over a year now, and he's always had problems with a specific and reoccurring ear infection. I have taken him to two different vets, and he has been incorrectly treated for ear mites between changing vets, and the only thing we've found so far is that it might be an allergy of some kind. I have changed his food to prescription Hills for food and skin allergies (with no extra snacks or scraps and sent in cultures on the gunk build-up and sent them to Iowa State University Vet Med with absolutely no luck. Do you think it could be dust mites, or another kind of air born allergy? Or is there something I'm missing?

That kind of itching would be unusual with an environmental allergy, if it is specific to Toby's ears. There are many medications that are available if environmental allergies are possible, and the food that he is on may take a few months to take effect.

Without examining Freddie I cannot say what the specific cause of the itching is, but you should visit your Veterinarian for an examination to check for infections, parasites or signs of other conditions which may be leading to itching or the formation of sores. Regards Dr Callum Turner DVM

It can take some time for an allergen to leave Lena’s system, you should continue with the dietary change for a few weeks and monitor for improvement; you should also bathe any sores with a dilute antiseptic. If a food allergy (or any other allergy) is suspected, you should discuss allergy testing with your Veterinarian to identify the allergen faster. Regards Dr Callum Turner DVM

Itching

I moved to the east side of Washington in 2019 with my cat. Shes never had an itching problem till we moved. When spring came I noticed she started itching after I took her out in the cat backpack a couple times. At the same time I had reactions too, the feeling of a million microscopic bugs crawling on me. No biting just absolutely annoying and no rashes. So since then I've been on habit of doing laundry. Recently I bought a silk blanket so I feel them less and silk pillow case. I can't afford a vet, I just wish I knew what I could do to help her.

Itchy, Fur Pulling, Bald Patches

My cat is allergic to dust mite, tuna, white and beef. She was permanently itchy and used to get bald patches behind the ears, under her chin etc. She also had chin acne. She is was blood tested so we know it is an accurate diagnosis and is now being successfully treated with homeopathy. WARNING many vets will treat biting at the end of the tails and fur pulling in the same area as “anal gland” problems. It is a painful procedure to have them emptied and it is unlikely there is a problem at all, it is just part of the allergy issue. Can’t recommend you find a good homeopathic vet highly enough. Animals respond brilliantly with all kinds of issues.

Scabby Itchy Skin

My cat has itchy areas of scabby skin around her tail and back, eyes and tummy. This seems to have happened since we moved house and removed a disgusting old carpet that had failed rubber underneath which had become a mass of greenish fine dust. Since then ,we are dealing with the dust. Should it be a dust allergy, will the symptoms reduce as we get the house-dust to a minimum?
