Young Sheldon S03e09 H255 May 2026

Sheldon’s science experiment for school involves observing a parasite (a tapeworm). But when Missy points out that he has never actually cared about a living thing before, he pivots. Hard. He adopts a stray cat. The logic? "If I can keep this cat alive, it proves I understand biology better than the teacher." The result? The cat hides in the wall of the garage for three days. Cue Sheldon trying to lure it out with laser pointers, algebra equations, and eventually, raw fish. (Spoiler: The cat only comes out for George Sr., because of course it does).
