Sure, who wouldn’t want a cat that’s both a speaker and a mood lamp? Keep the circuit tight by using a single 5V rail for a tiny 3‑inch 4Ω speaker module and a small LED driver that’s already got the LEDs wired in. Mount the driver and speaker on a flexible PCB so it folds inside the cat’s belly, hiding all the traces under the glitter. Use diffused polymer caps on the ear LEDs so they look like frosting swirls. Run one ribbon cable from the board to the power switch you can hide under the tail—no tangled wires, just a neat snap‑on. That keeps the vibe cute while the internals stay clean.
