Hello, Could someone please give me some advice? My cat appears to have gained a small grey growth beneath her left ear. It is like a balloon. Although it does not appear to be causing her much discomfort, she is not scratching at it and she is not off her food, I am somewhat concerned. We have had a lot of building work in our house at the moment and she is very timid and spends a lot of time hiding and I wondered if it could be stress related. Any help would be very much appreciated and would set my mind at rest. Thankyou very much. Jane
