Why Does My Domestic Shorthair Have a Bump on Her Nose? (Vet Answered)

Hi Sezen,

Thanks for writing in. Pixel looks gorgeous! I too know that challenge of life with a greedy kitty, so well done on getting some of that weight off! It's not always easy.

It's difficult to say for certain what the bump could be. If she's not bothered by it, it may simply be part of her normal anatomy, and as she's grown and gained weight, it's become more prominent as the subcutaneous fat layer has increased. It may also be some scar tissue from fighting, but I would expect it to be going up and down in size, be painful, and possibly leak fluid/pus if it was regularly being re-injured.

Unfortunately, we do also have to consider the 'c-word' as tumors and cancers are possible, particularly on a white nose. Squamous cell carcinoma, for example, is very common on white faces and ears, and tends to be quite slow-growing. I think the most sensible thing is to have your regular vet take a look. They may recommend taking an x-ray, or they may just be satisfied with a close inspection.

I would also encourage you to take some close-up images of Pixel's face and nose with something measurable beside it, like a coin. This makes it easier to objectively measure the size and shape of the lump over time.

I hope this helps!
