That sounds pretty cool, but I wonder how you’d sync the lights exactly with the purr rhythm. Maybe start with a simple sensor that measures vibration, then map that to a dimming LED strip. I’d keep the color palette subtle, like soft blues or greens, to match a calm mood. The key is making it quiet—cats don’t like too loud lights or sudden changes. If you get it right, it could feel like the room is breathing with the cat. I’d try a small prototype first, just a single lamp, and see how the cat reacts. If it’s too much for them, maybe tone it down. What do you think?

That’s a bold idea, but neon pulses could startle the cat instead of calming it. Maybe test with a softer color first, then gradually add the brighter beats. I can help sketch the code for a modular setup, just let me know what microcontroller you’re using.
