My senior cat has lumps in his ear. Are they serious or normal?

Can I send you a picture of what is in my cats ear so you can let me know what it is? He’s not in pain and rarely scratches his ear. No discharge or blood ever. It’s like these little lumps in the ear. I noticed he is hard of hearing too. But he is 18 years old...

These are most likely ceruminous cysts, which are essentially cysts filled with ear wax. We see this condition with a disorder known as cystadenomatosis in cats. These can be in the ear canals, on the ear flaps, around the eyes, mouth and occasionally the anus. Unfortunately there is no medical treatment for the underlying disease. If they extend down into the canals, the only treatment is total ear canal removal. However, the individual cysts can be removed with a surgical laser. I recommend taking Mario to the vet, so they can provide and accurate diagnosis and assess the extent of these. I hope that helps.
