Hello! I have a six month old kitten who just today began to keep his left ear sort of down and to the side. Upon looking inside, I have discovered a yellow/green pus-like substance on the furthermost portion of the inside of his ear. It is not deep inside, just right within a little crevice. It doesn't appear to have an odor that I can smell and he is not walking as if he is dizzy. There is no black residue in his ears whatsoever. His right ear looks perfectly fine, as does all my other cats' ears. I used a Q-Tip to gently clean the pus out of his ear, hoping maybe it was just earwax buildup and with it gone he would stop holding his ear funny. He has been napping upstairs so I figured I would leave him alone for a little. He has now come downstairs and was still keeping his ear down to the side and shaking his head a bit. I looked inside, and the pus is back. He is still playful and acting like his normal self, other than the weird head shaking and ear position. I'm wondering if this sounds like an ear infection or maybe just a wound from playing with the other cats that has become infected. His ear does not appear red or irritated. Any advice or input would be very helpful!
