Put a thread on hear about GP changing character and starting to be very vocal. Someone suggested she may be ill, am taking her to the vet next week as compared to my other guinea pig she is skin and bone. She has so much hair you can't notice it, but stroking her can feel all her back bone and ribs. V. worried, really don't think she used to be like that. She still seems to be eating and drinking so don't understand it!
