We got the following letter on our door from our apartment managers:

If you have a pet, please be considerate and pick up after them. Please take them outside to do their business. If [sic] has come to our attention that some are allowing their pets to do their business in the hallways. This will not be tolerated. Let’s make this a nice environment for everyone.

Yep, this is where we live.
