Hello, I have my 6 months old Baby neutered today, but he looks really tired, quite and painful. The vet said it is normal because he just got neutered and that he did not have any food since last night (as I cannot feed him anything 12 hours before he neuter and 12 hours after he neuter, so he still does not have any food now *sniff* the poor guy must be really hungry) And now he wont sit or lay down, and his back legs keep shaking. I dont know if this is normal, but the vet office is closed now, so I dont know what to do. I tried to make him rest, but he just keep standing with 4 legs and looks really painful. Even I take his favorite toys out or pat him, he has no reaction at all. It makes me sad when i look at him like that. Please advise!
