Schrödinger was a cat owned by Carter, named after the quantum mechanics theorist Erwin Schrödinger who proposed the "Schrödinger's Cat" thought experiment which theorized that a cat put in a box with poison in it would be observed to be both dead and alive at the same time. She gave the cat to the Tollan Narim as a gesture of friendship (1.17 "Enigma"). Narim used Schrödinger as an emissary before coming through the closed iris of the Stargate at the SGC at one time, before the Tollan were given a way to notify the SGC of their intent to visit (such as with a Sagan Institute Box or a GDO) (3.15 "Pretense"). We can only assume that the poor animal was killed when the Tollan's new homeworld Tollana was destroyed by the Goa'uld (5.09 "Between Two Fires").
