Hello. I am always concerned about an ulcerated nasal planum in a relatively young cat. This could be bacterial, autoimmune, fungal, or cancer ( less likely due to his relatively young age ). You really need to see your veterinarian for a minimum of a culture & to start antibiotics. If the antibiotics do not seem to be helping, than a biopsy will be necessary. Hopefully, he just picked up an odd infection & he will be back to his beautiful self soon. Thanks for contacting Petco Pet Education Center, formerly Petcoach.
