My cat is scratching its head a lot and it's red. What could it be?
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.
