Unfortunately my son accidentally dropped one of our guinea pigs the other day and she is in 'spinal shock' (nothing broken thankfully). She was dragging her legs but is now limping so is hopefully on the mend. She has been weeing quite a bit so I need to give her a wash but obviously need to be a bit careful due to her injury. We've only had them a few weeks and I haven't bathed them yet, so any tips or advice would be much appreciated.
