My cat has weird spreading spots on its ear. Should I be concerned?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | neutered | 11 lbs

These weird spots have been showing up on my cat's ear, not sure why. He's about 5 (was a feral kitten I rescued from a dumpster, around 5months old) but has had fantastic health and is in great shape ever since. Should i be concerned about this? The spots are spreading there are more today than there were last week.

Hello, and thank you for your question. Are the spots rough or crusty? Or is it just a discolouration of the skin? If there is a roughness to the spots, then I would worry about a possible skin infection (bacterial, fungal, or parasitic), and I would recommend taking Harlequin to the vet. They can perform tests such as a skin scraping or cytology to check for the underlying cause. At minimum, they may suggest a topical antibiotic and/or anti-inflammatory cream in case of an infection. If it is only a discolouration and he seems healthy and not itchy around the ear, I would monitor it for now unless the spots worsen or increase in number. I hope this helps, and that Harlequin is feeling well!
