The arrest of Julian Assange in London has raised a long list of serious questions about press freedom and the reaches of American justice.

But we wrote about those questions elsewhere. What’s left is a considerably more frivolous but widely asked question: What happened to his cat?

It is a concern of the tens of thousands of people who followed “Embassy Cat” on Twitter and Instagram, watching for more than a year as an indisputably adorable kitten crawled along Mr. Assange’s shoulder and sat in on meetings with his visitors. No matter one’s feelings about Mr. Assange, the cat, who had lived in the Ecuadorean Embassy with the WikiLeaks founder as he holed up to avoid capture, was a made-for-social-media star.
