Peachie's ears are either dirty or maybe she has mites. She has to go to the vet this week anyway,and doesn't show signs of scratching, shaking her head etc., but there is definitely some crud in there. How do you know? Thanks.
With ear mites there will be intense itching, not necessarily all the time but sometimes and most often if you look really closely you can see specks of white moving around if they have a heavy load of mites.
Poor baby...you can q-tip inside a little and then shake it over a dark sheet of paper...mites = wiggling around little dots. I bet she just has some dust and grime in there. The vet will know for sure. I think if it was mites, she would be pawing at her ears.
It is most likely dirt. Mites are terribly itchy and uncomfortable. I picked up a stray cat once that had them. The best way to tell is check them out under a microscope. I did an ear swab on one of the stray kittens at the clinic once and saw the little mites magnified at around 450x and they're nasty little bugs!!!
