My cat went out this morning at 7am and all seemed fine. When I came back home, I notice her nose was dark. I thought it could've been dirt, but after checking I noticed not only it is black, but also the hair looks shorter in the area. She was diagnosed with stomatitis a while back, but was checked recently and it all seems fine.
Her behaviour is the same as always, she's eating and using the toilet normally. She loves sleeping in sunny spots.
I'll be bringing her to the vet but all I want to know for now is whether it's an emergency.
The first photo shows her after and the second before I noticed the change on her nose.
