Last month I discovered this white kitten at my front door, wet and cold from icy rain we've been getting in our area. When no one claimed her, I decided to keep her. However, this will be my first cat as I have only ever had dogs. I had to bathe her as she was riddled with fleas, got her flea medicine and even had her spayed this month on the 3rd. This morning I noticed my cat was shaking her head alot and kept scratching her ears. I noticed a build up of brown... wax? I'm assuming. She's been inside since I found her and my dogs (2 chihuahuas) are all well kept and their ears are completely spotless so I don't believe it to be mites. Then again, I'm not sure. Can it be a possible ear infection? And does anyone know how mites are transferred?
