Bump on cat's ear

[csonsini]

My black cat has a little white bump on the outside of his ear, up near the tip. It looks like a tiny wart. There's another even smaller bump on the inside of the same ear.
It doesn't seem to bother him.
Any ideas?

Any lumps or bumps, no matter what size/shape, etc..should always be checked by your vet, always.

Get kitty seen promptly please.
