Ouch, Precious's ear looks so sore and painful. Perhaps you could make a home made collar for her to wear to stop her from touching it.
Sunny has a crinkled ear from a haematoma(Can't remember how to spell it sorry!) which she had before we adopted her. You can see her crinkled ear in the photo below.
I think Precious needs something though from the vets it's obviously bothering her so badly.
I'm praying for Precious and Jack & Sunny are sending happy feet and purrs her way _
