We have suddenly lost our 3yr old guinea pig. We introduced 3 new babies 6 weeks ago after loss of another older guinea pig, they seemed to of bonded well snuggle together etc the only thing I noticed was 1 of the babies was barbering her at times, no noticeable bald patche's etc. Has any one had any experience of this I honestly don't know if it was just her time or if there has been anything wrong.
