My feet are infallible cat vomit detectors. Our cats don’t often vomit but sometimes they have hairballs, or have eaten too much catgrass (we grow it inside in pots) or have gobbled their food. Generally if you hear it coming you can find it quickly. But sometimes it happens at night and my bare feet find it in the morning.
I saw instructions for 3-D printing these little signs, which did make me smile
You can also buy them on Etsy
I suffer from emetophobia (fear of vomit) but cat and baby puke does not bother me at all.
