Cat Masterson is a character in Regular Show. He appears in Cat Videos. He uses actors as cats so that he can create cat videos, but at times he tries to kill them. In the end, he turns out to be a cat himself and is taken away by animal control.
Cat Masterson has orange hair, that goes into a moustache, which is all connected. He wears a white long-sleeved shirt and an armless coat, black pants and a belt.
In his real cat form, he is a ginger cat who still has the moustache.
