Shay, I think it may have been the light or something. I just looked at both her ears, they are pink, and don't look irritated, but I'll keep checking them to make sure nothing funky is in there.
MMM, I can't remember when the last time you saw her was, but she was a smaller cat a couple of years ago. After she turned 2 she started filling out and growing a bit.
Thanks everyone for your lovely comments.
She's doing very well and really isn't too concerned about the gang.
