When I handle Jackson, I always flip him over to check him underneath (as he once had diarrhea, but thats another story!), well anyway, the other day when I did this, I noticed a little pink lump on his balls. I thought at the time I'll try and get a photo, so I put him down to get my phone, and then when I flipped him over again, it had disappeared. So I let it go out my mind. I've seen it a few times since, and tonight I saw it again.. if you imagine him on his back, its on the top of his left ball, sort of near the middle of the two. sometimes its there when I look, but other times it seems to disappear. I've just gone to look again now, to try and attach a pic to this post, had a good luck and a gentle feel around (poor guy!) but it wasn't there again. I'm really baffled by this! Anyone any ideas?!
