Hamilton goes to Angell Memorial tomorrow. If I can successfully get him into his carrier, which will be quite a battle, I'll be taking him there for a noon appointment. They'll keep him for two days to do tests on his heart and lungs and take blood. If all is well, he'll have the radioactive iodine shot and have to stay there for at least two weeks. If we brought him home sooner we'd have to flush all of his litter and keep him isolated from places like the kitchen and bedroom, which would be hard with four other cats in the house! He also isn't particularly great about using the litter box sometimes.
I know my heart will break leaving him there. The poor little guy will think I'm giving him away. Ironically, Angell Memorial is where he was adopted 12 years ago. Wish me luck!
