Hi I have a four week old male guinea pig who overnight is dragging his back legs. I took him straight to the vets and they said he must have been injured himself however I don't think this is the case. he was prescribed metacam for cats to help reduce any swelling he might have. I have read of other guinea pigs going off their back legs and heard it may be a calcium deficiency. The vet said if he doesn't get any better in 7 days it might be better to PTS but I want to try and help him the best I can. Has anyone had any experience of this in such a young piggy? Thanks
