|When your Naegleria is bigger than you, Primary Amoebic Meningoencephalitis is the least of your worries.|
These fabulous microbe-shaped critters, modeled here by not-to-scale cat figures, include the beaver fever parasite, E. coli, and a delightful variety of flagellate free-living protists. They're made by Etsy seller Mycrobe and are stuffed with genuine hi-test catnip. You can follow the cat toys on Twitter at @mycrobecatnip. Thanks to KMP artist @artologica for the tip.
