Sandy was neutered yesterday. At first, everything was fine. However, when the pain medication wore off, he was in a LOT of pain, and had to be taken back to the vet. Due to his age (3 years approx), he is having a more difficult time than a kitten would. He was given a tranquilizer and kept in the foyer, so he couldn't jump onto anything. He is doing much better today.
