Hi everyone, I'm very worried about one of my guineas. I got 3 about a month ago (they look no more than a year old). They were all doing great for awhile, but the past few days one of them has been acting strange. He's usually very active, running around and popcorning, but now he just sits still in his pigloo for long periods of time. He tilts his head over to the side, and when he does run around he looks like he's drunk. He staggers and falls over. Could he have some neurological problem? Is this common in guineas? Any help appreciated
