- The author's cats Noodle and Loaf live a deliberately low-tech lifestyle, having never used a robot litter box, automated feeder, or GPS tracker before this intervention.
- The author's partner installed a USB-powered 'On Air' neon sign above the living room litter box that lights up whenever either cat steps in — an idea the author initially took as a joke.
- The spare motion sensor came bundled with the cats' ceramic water fountain, which itself only activates when the cats approach for a drink, and was repurposed after the partner spotted similar setups on Instagram cat Reels.
- Practical drawbacks the author flags include easy accidental triggering when the sensor is mispositioned and a glaring reflection on the TV during tense movies.
- Noodle and Loaf have continued using the litter box without apparent concern despite the glowing sign — though the author notes the setup would be deeply unwelcome if inflicted on a human bathroom.
Why it matters: More lifestyle humor than hard news, but the piece inadvertently surfaces a real flaw in cheap USB motion sensors — they trigger too easily when mispositioned and, once wired to a neon sign, create a glaring TV reflection. For anyone rigging pet tech at home: the same $5 sensor that works for a cat fountain is twitchy enough to ruin movie night when repurposed for bathroom broadcasts.
