Any ideas?

So Haze has had this little lump on her ear for almost a week, it doesn't seem to hurt or bother her, I've seen this on cats before, pretty sure its a bug bite, but would like the input of others, and before you suggest going to the vets, please don't suggest that

It could be a bug bite, a small injury, a wart, or some other kind of skin node. I, myself, would just monitor it for the time being as long as it isn't bothering her. if it doesn't change drastically or get a lot bigger, just make the vet aware of it at a future vet visit.
