The grey squirrel has been classed as an invasive non-native species to the island and the States' spokesperson said no decision had been made about what the next steps would be if the squirrel was safely caught.

But the spokesperson added: "Every avenue will be explored to try to return the squirrel to a more suitable environment.

Return it? Isn't it invasive in all of Europe, with all of the countries in Europe that have it spreading through them trying to get rid of it too? Like, are you literally going to convey a squirrel across the Atlantic?

Then once you get there:

Import requirements for live animals vary by species but may include an import permit, health certificate, import inspection, quarantine, and in some cases, a contingency plan. Some aspects of the import process require payment for services rendered.

I mean, I hope that "more suitable environment" is a euphemism for a taxidermist's office or something.
