Why do bats have sparkly poop?
Bats eat a lot of bugs -- up to two-thirds of their body weight in insects daily for some species. There's an unexpected side effect of all that insect eating, though. Bat scat is described as " sparkling with insect exoskeletons." Generally the words "sparkling" and "faeces" aren't found together, unless you have a toddler that's gotten into a jar of glitter.
It's a diet of insects that puts the shine in bat guano. Insects' exoskeletons, or hard outer coverings, are made of chitin. Chitin is chemically a lot like plant cellulose; it's difficult to digest, and passes through a gut relatively unchanged. If you eat a lot of shiny insects, you are going to produce Twinkle Turds.
