Cat Got Your Brain is the fifty-eighth episode of Shaun the Sheep.
Two evil bungling alien scientists transport Pidsley the cat and Shaun aboard their flying saucer. Unfortunatley, a foolish error causes the aliens to swap the animals' brains around. Shaun and Pidsley are dumped back to earth, not realising they are in the wrong bodies - leading to much confusion around the farm before the aliens return to correct their mistake. At the end, everyone's brains were also swapped.
