Junior Guinea Pig
I have a chunky sow of 2 years, who is healthy and happy. She has a lump in her back with a centre which seems to ooze a very small amount of yellow fluid. The lump is about the size of a 5p piece. It doesn’t appear to bother her at all. She also is inclined to drink much more than the others in her herd. Should I be concerned?
