Known officially as the chief mouser at the prime minister's residence at No. 10 Downing Street, Larry will not be joining outgoing chief David Cameron and his family when they move out Wednesday.
The tomcat was a sentimental topic of conversation in Cameron's final appearance in Parliament as prime minister.
Cameron said he wanted to use the prime minister's question time session to end a rumor that he was not fond of the cat, which was brought to Downing Street from an animal shelter five years ago.
