Arcturus Aldebaran Powers, a magnificent F2 Savannah cat owned by the Powers family of Michigan, USA, was officially verified by the World Records Authority as the tallest domestic cat ever recorded, standing an extraordinary 48.4 cm (19.05 inches) tall. A Savannah cat is a hybrid of a domestic cat and an African serval, known for their tall, lean build — but Arcturus exceeded all known records for the breed and the species. Remarkably, Arcturus lived alongside another record-holder in the same household: the cat with the longest tail on a domestic cat, making the Powers family’s home one of the most record-breaking in feline history.
