OK, we have this rescue guinea pig. I'm guessing Reggie is about a year old. He's with a little bun as a cage mate. They are both the same size. Bun is doing great. However, Reggie is getting thin, and I am seriously worried about him! He's on the correct guinea pig diet. I don't feed any bad greens. And lately, I've been restricting his diet to only the guinea pig formulated diet so I know he's supposedly getting what he needs. Does he need deworming? He appears to be in good health with the exception of him getting thin. Anyone have any ideas? The only other thing I can think of is a possible intestinal blockage from grooming the bunny. Would this cause him to go thin? And would something like Papaya break up any blockage he may have without killing him?
