What's this grey mark on my kitten's nose that looks like fur?

I would recommend taking Snow White to a veterinarian. This can be anything from a bacterial infection to a fungal infection (like ringworm). They can take a woods lamp (it is like a black light) to see if it glows green. If it does it is ringworm, if it does not it still could be. Only 50% of all ringworm shows up positive with this test. Your veterinarian will prescribe medication to help resolve the lesions. I hope Snow White feels better soon and thank you for using Petco Pet Education Center, formerly Petcoach!

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.

Nose bleeds, balance issues and a growth on the nose are very worrisome signs that should be examined by your vet ASAP. Infections, systemic illness, neurologic issues, toxicity, something stuck in the nasal cavity, growths, tumors, etc can all be possible causes which would benefit from a complete exam. Your vet may recommend additional tests such as taking a sample of any growths, bloodwork, and looking in the nose itself to try and find the cause.

The mark on Cleo's nose looks like a bit of crusted fur. This could be due to a scab from scratching herself, or could be the start of a mild bacterial or fungal infection. As long as it doesn't seem to be bothering her, it's perfectly reasonable to keep an eye on it for a week or two before taking further action. If it gets better - problem solved! If it stays the same or gets worse, it would be best to have it checked out by a vet. During the exam, your vet may need to scrape a sample of skin cells to be examined under a microscope to get to the bottom of this issue. I hope that everything goes well!

I would recommend a vet visit. The picture is a little blurry but it may be infected. It could possibly be due to ringworm. The vet may want to do a skin scraping or fungal culture to determine what it is in the best course of treatment.

Trauma would be most common - either from rubbing on something, scratching himself, or potentially from fight wounds. If he has been itchy or if you notice other similar areas I'd recommend having David examined by a veterinarian. Occasionally skin infections from allergies can cause macular lesions.

It is difficult to tell from the pictures exactly what could be going on. However, crusty skin lesions can be due to parasite (skin or mite) infections, bacterial infections or even fungal infections. Your veterinarian can perform a skin scraping to determine the cause of the crustiness and prescribe appropriate treatment.
