I noticed yesterday morning that Pepper kept trying to scratch her ear. I picked her up and noticed a little bit of crusty stuff in her fur right under her ear. Knowing how she likes to get into things, I didn't think much of it - I just thought she had gotten into something sticky... Last night she was still scratching so I looked more closely and inside her ear was a dark runny-looking substance. So I got a q-tip and very gently tried to get some of it out (I didn't dig in her ear, don't worry, I just got what was showing on the outside). It looked kind of gummy and wet, and it was dark. After an hour or so I looked again and the spot I had clean was covered in the stuff again. Does anyone know what this is? The vet is closed by the time I get off of work. Can it wait until I can go on Saturday or should I take her to the emergency vet?
