Okay, today I am quite certain something is wrong. GP does not want to play much and is mostly just laying about looking very despondent. I called our regular vet who sees small exotics as well as traditional cats and dogs. I very much love and trust her, but I am not sure yet if she is cavy savvy. It does say they see small exotics though. I am going to take Hot Wheels this afternoon. Hopefully he is okay. I am so upset. So far he is still eating, but not as much hay. This morning he had about a quarter cup of mixed organic spring greens and he had a bit of celery. He has barely eaten any hay though and usually his rack is empty by now. He has been drinking water. I'm very worried. Please send good thoughts our way.
