The narrator says that he's so relieved and happy that the cat is gone from the house that he barely feels any guilt at all over the murder of his own wife, and that feelings of remorse disturb him but little.
求指教！老师，这个句子三个that从句，分别是干什么成分呢？
我的理解：
1 that the cat is gone from the house是做happy的形容词补语，表示缘由。
2 that he barely feels any guilt at all over the murder of his own wife是做so relieved and happy的结果状语，表示“这样…以至于”。 3 and that feelings of remorse disturb him but little这个也是作并列的结果状语。
2 和 3 是says的并列的宾语从句。
