Clear for mites and fleas, no one else is acting like this. X-rays of her head are clear.

The others will occasionally bit down on the poor baby's ears and not let go, either, which means I may have to separate her from the group.

She won't groom herself anymore so I have to bathe her every second day, she constantly scratches herself, and she shies away from love. She used to be my most squishy, lovey rat and this is heartbreaking.

Does anyone have any advice for me? I'm stumped and the vet is stumped. I'd at least like to make her as comfy as possible.

Other info:

She is a year old as of June 12. Un-spayed. Part of a 6 member mischief, and former Alpha, but I'm not sure now. White furred Himalayan.
