Genji

From Tardis Wiki, the free Doctor Who reference

Genji was a cat owned by Wesley Erickson.

After moving to a Floridian retirement home with his owner, Genji began associating with the three-legged cat Gramps. Not long after Wesley witnessed Gramps leading Genji and a group of other cats in a fight against a younger cat — apparently Gramps' past self — in which the younger cat lost a leg. (PROSE: Gramps)
