I agree with all Seredipity has said, it could be pain or more nerves because of feeling vulnerable.

With metacam, it can be quite harsh and cause stomach upsets too. It is always hard but I'd be considering her quality of life after you have had a chat with the more specialised vet. I don't mean to come over harsh at all, having rats they get a common thing called hind leg degeneration and they can be totally well but the extra energy, not being able to get around like they should does take its toll. Some I let go sooner than others, you get that feeling in your gut to "know".

Keep us posted and good luck x
