Why do my cat's ears have a red outline? Is it normal or serious?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Mediumhair | Male | neutered | 2 years and 2 months old | 11 lbs

I noticed that both of my cats ears had a red outline to them. He doesn’t paw at them often or anything more than normal. Curious as to what it is and how to treat.

Hi! It appears that you are seeing the blood vessels of Jasper's ear with good lighting. The ear does not look abnormal from the photo but if you see changes to the skin of the ear tips, swelling, pain, head shaking, hairless, or increased redness, he should be assessed by a veterinarian.
