When Alf went they couldn't find the necessary to start with and his poor wee arse was seriously bare when he came back. Didn't bother him though. I think he thinks it one less thing to wash.
Did make me laugh though when the heart specialist was so adamant that I needed to have him done. She was worried I would breed from him and that wouldn't be good given his heart defect. Bless her she thought he was a pure bred. At the time I didn't think he was so had no intention of breeding from him.
