Cat Morty Smith is an alternative version of Morty from a dimension where humans are cat-people, he appeared in Rick and Morty Issue 22. He is the son of Cat Beth, and the grandson of Cat Rick, he was present at Doofus Jerry's trial at the Citadel of Ricks before Doofus Jerry overpowered them.
Cat Morty is a cat-boy with brown hair and whiskers. He has light-colored fur, long cat-ears on his round head and a brown tail coming out from above his butt. His hands and feet are paw-like and, like his grandfather Rick, does not wear shoes.
Cat Morty was present at the Citadel of Ricks, in the courtroom of the Council of Ricks when Doofus Jerry was brought before them for assaulting a Rick. He witnessed them identifying Jerry to be from Dimension J19ζ7, deeming him to be an even larger idiot than regular Jerrys. When Doofus Jerry emerged from the Genetic Restructurer reeking of pheromones poisonous to Ricks, Cat Morty climbed up in the tree they have in the courtroom, later, he returned at home with his mother and grandfather.
