I'm not an expert or anything, but I used to have two gerbils and when one of them died, the other didn't do or eat much, and tended to sit in the same place for ages without moving and refused to come out of the cage. I think he was sad and unhappy :(

In my opinion, I think that a guinea pig should NEVER be SUPER skinny. Their tummy should be kind of fat. As a rule of thumb, a healthy fully grown Guinea pig should weigh around 1 kg.
