Hi, I noticed today that one of my guinea pigs is having a little trouble eating. He recently suffered a trauma when one of my other boars managed to escape his own cage and into the neighboring one. He was injured with a very large bite wound to his lower back. It was over the weekend and we couldn't get him to the vet until very late, and a slight infection had already begun to set in. The vet prescribed antibiotics and cream and now the wound is very nearly healed. Except now he seemed to be having trouble eating, as though he can't quite swallow easily. He doesn't seem hesitant to eat but he has lost weight. This little guy has been through a lot and he's much smaller than my other piggies. Any advice you can offer please.
