Why is my cat scratching behind her ears and losing fur, no mites?

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. Judging from the photos you have provided, I would suspect this to be a severe allergic reaction or something such as a cancerous skin condition of the ear pinna. I would recommend having a veterinarian examine this so that the most appropriate diagnostic and treatment recommendations can be made. Vampira may need a course of steroids to treat this if it is a mosquito bite hypersensitivity or other allergy. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

Hi, and thanks for your question. This could be due to an allergy, although it could also be infection or mites. The treatment would depend on the underlying cause. First of all, in order to rule out skin parasites, you will need to treat with a high quality flea treatment, then ask the vet to perform a skin scrape - this might reveal an infection or a mite infestation. If all of those came back negative, the next step is to treat the allergy symptomatically and try to discover the cause of the allergy. Three main type of allergies are usually affecting pets: food allergies, flea and parasite related ones and environmental type (allergens coming from trees, pollens, dust etc etc). Some medications can be given by the vet in order to repair any possible skin lesions (like steroids and antibiotics). Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further. If this answer was helpful please let us know, this will be used to improve our service!

The most common problem causing Milly's symptoms is a severe flea allergic dermatitis. Regardless I recommend brushing her to remove the old fur and skin, giving a bath with a hypoallergenic shampoo and using Advantage flea prevention on her. You can purchase it at PetCo. She may need antibiotics to heal the skin and your veterinarian will do an exam to determine the cause of her problems. They may run a blood panel in addition to determine if she is anemic or has a metabolic problem. Once they have a diagnosis they will give her the appropriate treatment and hopefully she will recover quickly. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Milly.

Hello and thank you for reaching out to Petco Pet Education Center, formerly Petcoach. If Mimi is scratching one ear more than usual, it is likely that she has an ear infection. Ear infections can be bacterial and/or fungal in origin. If left untreated, simple external ear infections can progress to middle or inner ear infections, leading to vestibular disease or even central nervous system signs. I recommend making an appointment with your veterinarian to have Mimi checked for an ear infection. He/she will likely perform an ear cytology, meaning he/she will swab her ear and look at the material under a microscope. This way, your veterinarian can look for evidence of bacteria and/or yeast and treat her accordingly. I hope this is helpful!

Midnight could have allergies, fleas, or a bacterial skin infection. Inspect her for any fleas and then treat with a medication, like Revolution, Bravecto, or Frontline. If she has allergies or a skin infection then she would need to be treated by a vet with an antihistamine, corticosteroid, and/or an antibiotic. Some cats also pull out hair from stress so you could also try a Feliway diffuser/spray and talk to your vet about an anti-anxiety medication to help.

Thanks for using Petco Pet Education Center, formerly Petcoach! This is likely due to allergies. Benadryl is good as is prednisolone for example. However, these are only going to help with the itch temporarily. However, it is crucial to get rid of the allergic component and treat the allergy as if not, the itch will continue. Also, it is crucial to treat the likely secondary infection. There is no at home treatments as the other medication that can be used in cats for this is a prescription medication called prednisolone. One thing you can do at home besides dealing with the possible allergies is using an e-collar which you can get from your local pet store or online to prevent any further self-trauma. It really comes down to figuring out what is causing his allergies so that they can be treated or the specific allergen avoided. There are many things that can cause allergies though in most cases they can be broken down into 3 big categories: flea, food and environmental allergies. Allergies are usually worked up in a stepwise fashion starting with flea allergies as this is the easiest and cheapest to take care of. If not on a flea preventative, then it would be a good idea to get started on one. If already on one then it would be a good idea to change to something else (there are many new products out in the market). If not improved in 1-3 months then it is time to move on and check for food allergies by switching to a novel diet (new protein and new carbohydrate). If that does not seem to be the issue then you are left out having to check for environmental allergies which require blood and/or skin tests. Allergies can be very frustrating to deal with at first but so rewarding at the end when we are able to treat them effectively!

Scratching around the ears or eyes may indicate an allergy, or may even indicate a problem with the ears themselves such as an infection or ear mites (very common in cats). Signs of [ear mites](https://www.petcoach.co/cat/condition/ear-mites/) include dark or dirty debris that is black or deep red in appearance, or you may see other debris that is foul-smelling in the ears. Ear mites and infections usually require a sample being taken by the vet to determine the exact cause, as well as a regimen of [cleaning the ears](https://www.petcoach.co/article/how-to-clean-your-cat-s-ears-what-you-need-to-know/) with a medicated cleaner for 7-10 days. Ear mites can be spread to other pets, so treating any other dogs or cats in the house at the same time is best. If the ears are clear but you are seeing redness, it may indicate an allergy, or even possible problems such as [ring worm](https://www.petcoach.co/cat/condition/ringworm/) (which appear as a red "target" ring that will gradually increase in size over time, and IS contagious to other pets and people). Your vet can provide you with an allergy medication dosage to treat minor allergies, or may ask you to bring in your cat for an exam if you suspect ringworm or other skin infections.
