My 17-year-old cat has a hard brown spot on his nose. What is it?

Thanks for using Petco Pet Education Center, formerly Petcoach! This is possibly an infection. However, this is a somewhat common location for a tumor in cats as well. I still think that a focal infection or traumatic lesion is more likely. You can use a topical medication like Douxo 3% PS pads which you may find online. You can apply this to the affected area twice daily for 2 weeks. If this does not resolve or appears to be progressing, have Lovey evaluated by your veterinarian for further assessment and treatment. Good luck and have a great day!

From the pictures, it looks as though what you are seeing may be from trauma. Cat scratches to the face commonly occur on cats that are outdoor cats. Many times the hair will not grow back and the cat will be left with a small scar. If canto is indoor only and the nodule is raised, I would say get a vet to examine him to see for sure what it may be. It could be from a bug bite or a skin tumor of some type. If you cannot get to your vet right away, I would say just monitor for now and if it worsens get him seen sooner. It does not look infected or swollen from the picture. I would monitor for signs of infection which may include swelling, redness, painful to the touch, discharge, etc. I hope this helps! Please feel free to contact me with any further questions or concerns you may have. I am also available via consultation if needed.

Thanks for using Petco Pet Education Center, formerly Petcoach! This looks very much like a traumatic injury to his nasal planum. When that layer of tissue becomes exposed like that, they can be more at risk of developing infections. For this reason, it would be indicated to have Boo evaluated by your veterinarian for further assessment and treatment. They would be able to examine the area and potentially prescribe antibiotics to avoid an infection. Good luck and have a good night!

It looks like he may have a dermatitis on his nose which could be secondary to a bacterial infection, trauma, allergic reaction, or possibly a fungal infection. He should be examined by a vet to determine the cause. Your vet can do a culture, if needed to help diagnose.

Hello, as you may now cancer can only be diagnosed by looking at the cells of the area in question. Certainly, we can get a suspicion for cancer by assessing the gross appearance of the area in question. This means that although looking at Blue's nose I don't think it looks very aggressive to be considered a cancer, we are unable to tell unless we sample that area. Cats can get pigmentation changes with age, so this may very well be a normal change associated with his age and nothing you need to be concerned with. I would recommend monitoring the area for progression of this pigmentation change or any evidence of mass, ulcer, or thickening of the nose which would be more concerning for a cancer. Hope this helps and best of luck.

This appears to be just a change in color of the hair alone. No worries. THe haircoat in kittens often does change as they get older. As long as the skin itself looks good as you part the hair, there is no concern. : ) Thanks for visiting Petco Pet Education Center, formerly Petcoach! Take care. : )

Thanks for using Petco Pet Education Center, formerly Petcoach! It is hard to know without being able to evaluate Puss and see it. This is most likely a benign or malignant nodule. This is most of the time differentiated with a test called a fine needle aspirate which is easy, cheap and pain-free. Sometimes, a biopsy is required for a diagnosis. Have Puss evaluated by your veterinarian to have this test performed to try to sort out what the diagnosis is so that the best course of action can be determined. Keeping my fingers crossed that it is something benign!
