For a couple of years she has had quite a big cyst on her side, we took her to the vet and the vet said she would be fine. It flared up really bad last week so we took her to the vet and the vet said the surgery would be extremely risky for her so we decided to leave it, today I noticed her chewing the cyst and when I took her out of her cage for a cuddle she started jumping from my arms and scratching at me which she's never done, and now she's making a very weird kind of grunting noise which I've never heard before. It only started after I put her back in her cage though. It sounds extremely graspy and I'm very worried. she has been eating and drinking as usual but she won't stop making the grunting noise and biting her cyst. Can anyone help or give advice?
