Rosierum
Adult Guinea Pig
Now Rosie and Rum are around 15 months old I am assuming they are fully grown but I am a little worried about Rum. Rosie has always been the larger of the two and was at least 200g larger. My assumption was that Rum would catch up but now Rum has settled at around 930g whereas Rosie is a whopping 1270g and growing still. I'm worried Rum is underweight. Should I supplement her diet away from Rosie?
