Booboo the cat was a stray, wandering around in Guelph, Ontario in Canada.
Someone brought her into the Guelph humane society. When the employees there checked Booboo’s microchip* to see where she was from, they found something that surprised them.
It turns out, Booboo was from California, in the United States–more than 3,000 kilometres away. She had gone missing in 2013, four years ago.
