Thanks for the suggestion, MR! I have actually started to check for plugs and have done a few cleanings. He is able to clean himself down there, however I find he struggles with it and will sometimes give up (as he tends to flop over). He's pretty smart though, I've noticed him starting to go to a corner of the cage whenever he cleans himself (so he's able to prop himself up). It's definitely something I've been keeping an eye on though...
As for the age, you could be right... it's hard to say. They looked to be around 8 months when I first got them as they were smaller & pretty lanky (especially Polo). They each gained about 80-100g with me, but their past is unknown..so for all I know, that could have even been a nutrition deficiency or something.
