My kitten is now 4 months old and a couple of weeks ago I noticed that a dark spot had appeared on her nose. I took her to the vet and he said that it was just pigmentation - nothing to worry about.
She also has many darker spots on the roof of her mouth which the vet says are normal.
I do notice black mucus often appears in her nostrils, but the vet says that it is just dust from our house that she inhales, although this does not happen with my other cats - so I'm not sure about that...
Hi Sarah... thanks for visiting and asking. Your concern is admirable. I like that. You are one of us!
I think the vet is right. Certainly pigmentation on the nose and inside the mouth is perfectly normal. I made a posting about black pigmentation on the gums as people are sometimes concerned about this. The same principles apply to inside the mouth.
My cat Charlie has black pigmentation inside his mouth too. He has three legs.
As to the "black mucus" from nostrils, I am not sure. If everything else looks fine, meaning your cat is healthy, eating properly, going to toilet properly - in short showing all the usual signs of good health, then I would not worry but watch.
It may be that you are misreading the nature of the liquid coming from the nose. I suspect the vet is correct on this one too.
Your kittens looks adorable by the way - nice photo. Nice blob of black pigment on the nose...:)
