Do you have the funds to Spay her? it is possible that it could be linked to her hormones. SarahD has a rat from Eyohkay, that was horrible to other rats, and humans, Sarah took her in, had her spayed (I believe because she spays all her pets, not because it was thought that the issue was hormonal) and the vet said she had angry ovaries. After her spay, she tremendously changed. She now has a boy harem of her own, and Sarah can now hold her, and not be afraid of losing body parts.
