I first noted these growths starting to grow on one of my rats ears about 3 weeks ago now. I wasn't worried until i found the first small growth on the ear of another rat today.

Any body know what these are? I have tryed researching the subject and the only thing I have come up with is that they could be caused by a rare form of rat mites.

Any body know for sure what these could be and how I can treat them?



Thanks
