Pitcher plant doubles as toilet.

Jeez, a little privacy for the tree shrew, please?? From Live Science:

When you gotta go you gotta go, and for small tropical mammals called tree shrews, a pitcher plant serves as a handy toilet, new video research finds.

The jug-shaped plants make out just fine, too: They use the shrew's feces as a much-needed nitrogen source.

Most pitcher plants are carnivorous, trapping ants and other insects that slip down the sides of the pitcher into a pool of digestive enzymes. The new finding, published online June 10 in the journal Biology Letters, reveals at least one type of pitcher plant "feeds on" the poop from tree shrews in lieu of insects.

"Basically it's a toilet complete with a feeding station," said study team member Jonathan Moran of Royal Roads University in British Columbia.
