Thanks so much for your help. After I wrote, wetried holding her to see if there was anything around her mouth, butshe never likes to be held so she squirmed herself off. She ran underthe rocking chair and wouldn't come out. She kept biting anyone thatcame near her and then she started thumping and honking at us. We lefther alone for a minute so she would come out, and she finally did. Butthen she started chewing carpet, and she just seemed nervous.We found a couple clumps of fur in her cage, which we have never seenbefore. My sister thinks that shes biting her underside, and then itgets caught in her mouth. We called the vet, she said she really didn'tknow what it was, but it sounded like anxiety. But the more we watchedher, the more odd she got. She just wasn't herself. We called the vetagain and asked if we could bring her in, but they said they had 2emergencies coming in and they were just too booked. We called anotheranimal hospital and then said to bring her in. My sister just left withher, so I don't know whats going on now.
She hasn't been spayed yet, we were looking into different vets to doit, she's been going through mating frustration, tearing up her cageevery night and biting us if shes in a bad mood, but nothing this weirdbefore.
