Wrong Zeno.

The one in the cartoon is Zeno of Elea, who lived a century earlier. He was discussed iun Hop episode 8.

Stoic Categories?

Aristotle had his categories and the devotees of Plato loved to critique them. Plato himself seems to have one set in the Sophist and another in the Philebus. Does any Stoic have a another, rival set of categories? (If one did, I would guess it would be Chrysipus.) If not, then is there a reason that a Stoic wouldn't need categories of the sort Aristotle and Plato had?

Stoic categories

Yes, they did, sort of. They have a classification of things with "something" as the highest class, divided into incorporeal and corporeal; the former subdivided into lekta, void, place and time, the latter into different kinds of body (e.g. body that is qualified in a certain way). This is all laid out in sectiom 27 of the Long and Sedley volume on Hellenistic philosophy.

Having said that this is more of an ontological classification and not obviously doing the same work as Plato's greatest kinds or Aristotle's categories. But I think it's the closest they have to what you mean.
