My cat is scratching her ears raw. How can I stop it before the vet?

This could be an indication of infection (bacterial, fungal, mites). She would need to be physically examined by your veterinarian for confirmation. A swab of the ear can be examined under a microscope in the clinic to make the diagnosis. The appropriate medication or treatment can then be dispensed or administered. IN the meantime, place an e-collar (cone) on her to prevent excessive scratching or rubbing.

Poor Missy looks like her skin is quite irritated! She requires a visit to the vet to determine the source of her itchiness. She could have an infection in her ear (bacteria, yeast, or both), ear mites, or allergies (to something in the environment like pollen/dust or to food) that is causing the inflammation. Your vet can look down inside the ear and possibly take a swab to examine under the microscope, and prescribe the appropriate treatment for her. Placing an e-collar on her until your vet is able to see her will help decrease the self-trauma she is causing.

Oh my goodness, those hats are so cute! The problem with the hats is that typically cats hate wearing them, and you might have a lot of problems keeping one on Luna. I found a website called Pampered Whiskers, and they sell hats for cats. I will put the link below for you to check them out. You might also consider using an inflatable recovery collar for her instead of the traditional Ecollar. It looks like a donut, and it doesn't come out past her face which will keep her from bumping into things. I found one on Amazon, so I would google "inflatable recovery collar" to find it. Finally, I would make an appointment her vet to diagnose the cause of her itching her ears (it could be an ear infection, mites, fleas, or allergies) so it can be treated. Best of luck, I hope this helps! https://www.pamperedwhiskers.com

It is definitely an injury but whether or not he did it to himself or it was due to another animal I cannot tell. I do not think there are any bugs there. He may be scratching the ear due to an inner ear infection. I suggest you take DJ to your vet for an exam because is there is an ear infection or something down inside the ear canal you cannot fix/treat that at home. In the meantime you can apply a thin layer of antibiotic cream to the ear twice a day and I suggest you put a "cone" collar on him so he stops scratching the ear and making it worse. https://www.amazon.co.uk/Recovery-Collar-PETBABA-Padded-Elizabethan/dp/B00U7DTNB2/ref=sr_1_3?s=pet-supplies&ie=UTF8&qid=1517593656&sr=1-3&keywords=cat+elizabethan+collar Hope this helps. Best wishes.

The most common reasons that cats scratch at their ears are infections or infestations with ear mites. Ear mites can be treated by several different medications, some of which are over the counter and others that are prescription only. If there is an infection, an antimicrobial flush plus cleaning would be needed to clear up the affected ear. Steroids might also be warranted to assist with some of the inflammation and discomfort associated with the infection. Keep the e-collar on for the time being until you have resolved the problem. Sparrow will only make it worse as soon as you remove it, as you have already noted.

I am sorry Muchacho is not feeling well. Yes, you can buy an e-collar typically over the counter at your local pet store. This would be a good idea if Muchacho is causing injury to his skin. However, if he is really itchy I would recommend taking him to the vet for treatment of the ear mites and maybe antibiotics for his skin. Typically the ear mites will not resolve just from being cleaned. I hope that helps

This is probably due to a severe allergy, although it could also be fleas or mites.

 First of all, in order to rule out skin parasites, high quality flea treatment is given. It sounded like your veterinarian has done it already. The next step is to treat the allergy symptomatically and try discovering the cause of the allergy.

 Food can be indeed one the most common cause of it. Some medications can be given by the vet in order to stop the chewing and repair the skin lesions (steroids and antibiotics usually). 

There is also a nice topical spray available, it's called Cortavance and you can get it at the vets.

 Hopefully you will see some results after all this, if not you and your vet should consider starting on a long term allergy treatment.
