Junior Guinea Pig
For a very long time (possibly 1-2 years) I've noticed that my pig has lumps behind his arms where there is a lot of excess skin. In his right armpit, the lump is a lot bigger than the tiny one in his left. I'm positive it's just a fatty pocket in his body, as the lumps have not increased or decreased in size and I'm pretty sure have been there since birth. He is not affected by them at all and is very happy and healthy. I'm just interested in what these, mostly unnoticeable, lumps are and if anyone else's pigs have them!
